| |PDF (1066 KB)

An experimental comparison the performance of a far infrared (FIR) waveguide laser operating near the 1.2 mm wavelength with two different types of waveguides has been performed. The results indicate that a tall metallic rectangular waveguide has a lower threshold and produces more linearly polarized FIR power than a circular dielectric waveguide of comparable size.

A simple analytical expression for the reflectivity of the cleaved facets of DH semiconductor lasers is compared with numerical results, and reasonable agreement is found. The analytical result is conveniently written in terms of waveguide parameters and thus gives a valuable tool for analysis of DH lasers. View full abstract»

An analysis of the sensitivity of InGaAs/InP bipolar heterojunction phototransistors (HJPTs) used in pulse code modulated optical communication systems is presented. The minimum detectable power of an HJPT biased at the optimum level is found to increase linearly with bit rate B while because of the fixed transconductance of the FET amplifier, the minimum detectable power of a p-i-n FET inc...

| |PDF (611 KB)

The effect of high spontaneous emission on the extinction ratio of modulated laser-diode signals is discussed. A calculation based on the spectra taken from oxide-defined narrow-stripe lasers at on' and off' levels shows that high spontaneous emission at the `on' level can degrade the apparent extinction ratio of the source, due to material dispersion in optical fibers, and affect transmission b...

Describes a kinetics model for e-beam excited XeCl lasers using Ne/Xe/HCl gas mixtures. The model has been validated by comparison with measure transient absorption in Ne/Xe mixtures, as well as by comparison with measured laser performance under a range of conditions. A key feature of the model is the inclusion of a fast three-body charge exchange process between Ne2+... View full abstract»

Constricted double-heterojunction (CDH) diode lasers are presented as the class of nonplanar-substrate devices for which the laser cavity is one of the least resistive electrical path between the contact and the substrate. Various types of CDH structures are discussed while treating three general topics: liquid-phase epitaxy (LPE) over channeled substrates, lateral mode control, and current contro...

Coupling between two uncoupled waveguides in proximity can be affected by introducing a third waveguide between them. One advantage of this scheme is that it can eliminate the need for bends. Another advantage is the resulting improvement in the shape of the transfer characteristic. Improved sampling and tunable filter operation of this new structure are also shown.

Considers phase conjugation through degenerate four-wave mixing in a Λ-type three-level system under certain simplifying assumptions, the most restrictive among them being the assumption of symmetrical detuning of the pump from the two lower lying sublevels. When compared to an absorbing resonant two-level system, it is found that significantly higher values of the phase-conjugate reflectiv... View full abstract»

Refractive index changes have been produced in a silicon crystal by excitation of electron-hole pairs with an Nd-YAG laser. The index changes were detected by observing the temporal shape of an initially smooth pulse after transmission through a silicon Fabry-Perot etalon. The index varies during the pulse with the absorbed energy and tunes the Si cavity over several resonances. The transmitted pu... View full abstract»
