  • Anomalous tuning of single mode AlGaAs diode lasers

    Publication Year: 1982 , Page(s): 1990 - 1991

    Deviations from the normal tuning of a TJS AlGaAs diode laser have been observed. In the usual situation, the emitted wavelength of a single mode diode laser as a function of temperature is described by a "staircase" function, that is, the tuning curve consists of regions of smoothly increasing wavelength as a function of temperature separated by positive wavelength mode hops. We have observed a t... View full abstract»

    A general theoretical description of modulated laser fields and power spectra for a current modulated single-mode laser is derived, taking into account both the intensity and frequency modulation (IM and FM) of the emitted light. The theory relies on an explicit knowledge of the modulus as well as the phase of the current-to-frequency modulation transfer function for the laser. Numerical examples ... View full abstract»

  • Optical bistability based on self-focusing: An approximate analysis

    Publication Year: 1982 , Page(s): 2016 - 2022

    Calculations are presented which describe approximately the behavior of optically bistable devices based on the self-focusing of light. A simple heuristic calculation and a more complicated calculation which incorporates saturation of the material nonlinearity are presented. Both give a good qualitative description of situations in which a single hysteresis loop is observed. More complicated types... View full abstract»

  • Nonlinear index effects due to pump laser bandwidth in Raman conversion

    Publication Year: 1982 , Page(s): 2056 - 2059
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (488 KB)  

    In the Raman process, the finite pump bandwidth and the medium bandwidth can result in a nonlinear index effect depending on the pump intensity. This can result in spectral dispersion and, more importantly, introduce Stokes wavefront errors due to nonuniform pump intensities. In this work, we derive an analytical expression for the nonlinear index as a function of wavelength for a flat top pump sp... View full abstract»

  • Polarization coupling in kinked single-mode fibers

    Publication Year: 1982 , Page(s): 2032 - 2039

    When a fiber is stretched over a small ridge on a drum, the modifications of the distributions of curvature and of lateral force near the ridge induce extra birefringence in the fiber. Many such kinks, distributed randomly along a high-birefringence fiber, degrade the polarization-holding quality of the fiber. A theoretical analysis of these effects and pertinent experimental results are presented... View full abstract»

    This paper presents the theoretical and experimental results of a study on laser diode mode partition noise. Laser diode mode partition noise is evaluated by mode partition constants which indicate the degree of variance in longitudinal mode power. The relationship between the mode partition constants and laser diode characteristic parameters is clarified using rate equations. The mode partition c... View full abstract»

    We calculate operating characteristics of high-sensitivity high-speed In0.53Ga0.47As/InP avalanche photodiodes (APD's). We find that significant photocurrent gain is obtained for a total fixed-charge density of \sigma _{\tot} > 3 \times 10^{12} cm-2in the depleted InP and0.53Ga0.47As regions. To obtain hi...

  • Relaxation oscillations and stability

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (424 KB)  

    The phenomenon of relaxation oscillations is reexamined from the viewpoint of stability theory. We show that undamped relaxation oscillations with modulation depths of unity can be understood as centers at zero photon density. In addition, we show that the threshold pump rate and the criteria for eliminating relaxation oscillations can be obtained from the stable node conditions at the nonzero pho... View full abstract»

    Flashlamp pumped coumarin 153 and rhodamine 110 dye lasers have been passively mode-locked for the first time using the saturable absorber 2-(p-dimethylaminostyryl)-benzthiazolylethyl iodide to produce pulses as short as 3 ps with pulse powers of up to 5 MW in a spectral range not previously covered.

    Strong far-infrared (FIR) lasing action has been observed in hydrazine optically pumped with isotopic CO2lasers and the N2O laser. The wavelengths of 13 new laser lines have been determined. The results of a recent infrared-microwave double resonance study of hydrazine have been used to assign the transitions involved in the production of five of these new lines and nine of t...

    Spatial hole burning (which has been advanced as a cause of kinking, multimode operation, self-pulsation, and other effects in double heterostructure lasers) is shown theoretically to be appreciably suppressed by highly conductive confining layers. View full abstract»

  • Interaction of three coherent fields with Doppler broadened serial four-level systems: Application to four-level FIR lasers

    The semiclassical density matrix treatment is applied to serial four-level systems for the steady state. Phase and energy relaxations as well as Doppler effects and M degeneracy are accounted for. The calculations are restricted to parallel polarized fields, avoiding problems of quantum interference. The formalism is used to calculate the gain spectra of differ... View full abstract»

    We present a very simple and accurate numerical method for calculating the cutoff frequencies of arbitrary refractive index profile optical fibers, including discrete numerical data from profile measurements. From Maxwell's equations we derive a transmission line equivalent circuit for any mode of an optical fiber which is cutoff frequency dependent. The problem of finding the cutoff frequency of ...

    Harmonic generation and frequency mixing in nonlinear media pumped by subpicosecond pulses are studied. The propagation and interaction of subpicosecond pulses in a dispersive medium is influenced by group velocity "walk through" and spreading of the light pulses. The amplitude and spectrum of the N th harmonic are calculated taking into account both the group ... View full abstract»

    The dynamic behavior of electrooptic bistable devices with delayed feedback is investigated theoretically and experimentally. The operation principle of the system is analyzed by the method of iterated maps. Stable, bistable, periodic, higher periodic, and chaotic solutions are discussed and realized experimentally by using an integrated Mach-Zehnder interferometer on LiNbO3as a basic n...
