    A fully quantum mechanical theory of diode mixers which includes quantization of the external circuit is presented. We find that Tucker's theory for SIS mixer conversion efficiencies is correct, but that his expression for the measurement noise must be augmented by an amount corresponding to half a photon at every frequency to which the mixer responds. Noise in high quality SIS mixers is shown to ... View full abstract»

    The theory of broad-band forward Raman amplification is presented. An exact solution for the pump and Stokes fields is derived in the limit of negligible population transfer, negligible linear dispersion, an arbitrary number of axial modes with mode spacing much larger than the Raman linewidth, collimated-beam ray optics, and arbitrary Raman conversion. It is shown that if the incident pump and St... View full abstract»

    The role of the Zeeman effect for the power enhancement of a small-bore argon ion laser (488.0 nm) by applying the transverse magnetic field has been investigated both experimentally and theoretically. The σ-polarized laser has a larger output power than the π-polarized laser in the wide range of magnetic field strength. Specifically, at weak magnetic fields, enhancement occurred only fo...

    High average power frequency conversion using solid-state nonlinear materials is discussed. Recent laboratory experience and new developments in design concepts show that current technology, a few tens of watts, may be extended by several orders of magnitude. For example, using KD*P, efficient doubling (> 70 percent) of Nd:YAG at average powers approaching 100 KW is possible; for doubling to th... View full abstract»

    A simple argument to maximize the average output laser power in a single passage FEL device is presented. The optimization parameter is the undulator number of periods. The optimum values to get both maximum gain and average power are indicated and are shown to be different. View full abstract»

  • Guided wave characteristics of metal-clad graded-index planar optical waveguides: Analytical approach

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1488 KB)

    The complex eigenvalue equations of metal-clad graded-index waveguides are generally solved by numerical methods. The role of waveguide and material parameters in determining mode dispersion and attenuation becomes difficult to elucidate. We describe a perturbative method of solution which is suited to the class of waveguide in which the guided field is described analytically. Mode dispersion and ... View full abstract»

    The characteristic modes of coupled waveguide arrays with a simple layered structure are examined using the approximate coupled wave theory. It is shown that evanescent waves may arise from total internal reflection at a boundary between two semi-infinite arrays. The transmission and reflection coefficients for this process are derived. If a suitable, finite, array is sandwiched between two semi-i... View full abstract»

    We investigate the saturation effects of power broadening, Stark shifting, and population transfer on Stokes conversion in stimulated Raman scattering. We do not make the usual rotating wave approximation because the detuning from the next electronic state is assumed to be in the optical regime. Retaining the counter-rotating terms allows an exact determination of the pump and Stokes indexes of re... View full abstract»

    The Hermite-Gaussian periodically focusing beam solutions of the scalar paraxial wave equation with quadratic index variation are appropriate for rectangular coordinates. One expects the solutions appropriate to cylindrical coordinates to be LaGuerre-Gaussian multifocusing beams. The phase shifts of these solutions appear not to be available in the published literature. In this note, we present an... View full abstract»

    A silicon film sandwiched between a sapphire substrate and a silver layer is used as nonlinear optical waveguide. Light is coupled in the guide by a grating coupler which has been optimized. This device presents fast switchings under a nonlinear regime. A theoretical analysis taking into account both electronic and thermal refractive index variations in silicon well describes the experimental resu... View full abstract»

    The refractive-index profile of dual-mode optical fibers which makes possible dispersion-free operation at 1.55 μm wavelength is proposed. The refractive-index profile is synthetized using methods of quantum mechanics and numerical procedure. Optical fibers with this refractive-index profile have a core diameter of about 23 μm that is much larger than the core diameter of conventional si... View full abstract»

    We apply a formula for the small signal gain of a dye laser amplifier (obtained and verified in a previous work) to the case of a transverse pumped R6G amplifier. We trace a set of curves as a function of dimensionless parameters which give the gain for any combination of the parameters characterizing the amplifier (dye concentration, active length, etc.). The curves can be applied to design dye l... View full abstract»

    Gain coefficient measurements of a MAGPIE (magnetically stabilized, photoinitiated, impulse-enhanced, electrically excited) coaxial CO2laser discharge are presented. The effects of gas composition, input power, pulser ionization, and magnetic field on gain are examined. Measurements of the radial gain profile and saturation intensity are also discussed. A maximum small-signal gain of 0.... View full abstract»

    We derive the nonlinear wave equation for an envelope of an electromagnetic wave in a monomode dielectric waveguide. Concrete examples are given for a single-mode optical fiber where the coefficients of resultant nonlinear Schrödinger equation with higher-order dispersion and dissipation (both linear and nonlinear) are given in terms of properties of the eigenfunction of the guided wave as we...

  • Transient regime of a dynamic distributed feedback laser: Theory and numerical analysis

    A semiclassical treatment of transient behavior of a gain-coupled, distributed feedback laser is developed. The nonlinear response of the lasing medium to the spatially periodic pump and the effect of self-induced grating are involved in the theory. The influence of a noise signal value on the generation kinetics is demonstrated. The possibility of practically unidirectional lasing is also shown. View full abstract»

    A theoretical and experimental study of a CW CO2laser pumped Raman NH3amplifier at 12 μm is presented. Experimentally we demonstrate an amplifier power conversion efficiency of 30 percent, which is the highest reported to date for any optically pumped system in this spectral range.

  • Material selection for double heterojunction lasers--A higher bandgap does not necessarily mean lower refractive index

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1056 KB)

    Double heterojunction (DH) lasers are composed of a lower energy bandgap active layer sandwiched between higher bandgap cladding layers, and the refractive index of the active layer has to be higher than that of the cladding layer. A number of published papers are based on the belief that higher bandgap materials necessarily have lower refractive indexes, so that the correct-bandgap DH structure a... View full abstract»

    A theory for strongly coupled waveguides is discussed and applied to two- and three-waveguide couplers and optical wavelength filters. This theory makes use of an exact analytical relation governing the coupling coefficients and the overlap integrals. It removes almost all of the constraints imposed by a simpler and approximate coupled-mode theory by Marcatili. It also satisfies the energy conserv... View full abstract»

    A new model for the inherent electrical state of the tandem laser is presented. The electrical coupling between the sections is known from experiments to have a large impact on such a laser. In contrast to earlier rate-equation analysis, our new model allows for an investigation of this influence. In this paper we present results from a theoretical study of how the bistability depends on various p... View full abstract»
