    The effective index method is very useful for studies of waveguides with index variations in both directions perpendicular to the direction of propagation, e.g., semiconductor lasers. In this paper we investigate the case of nonplanar layers and simultaneous presence of an index perturbation. The accuracy of the first order expression is investigated and formulas for the higher order terms are giv... View full abstract»

    The refractive indexNof lead-tin-telluride is calculated for frequencies near the fundamental absorption edge. The contribution toNfrom electron states near the band-edges is calculated more exactly than in previous works and a new expression for the contribution from the high frequency region is proposed. Good agreement is obtained between our calculations and experimental r... View full abstract»

In this structure we separated the reflecting mirror from the p-side electrode in order to increase the reflectivity. Threshold current was 90 mA at 77 K and the operating temperature has been raised up to -85°C. The cavity length was 7.5 μm and single longitudinal mod... View full abstract»

    -An approximate analytic model of a homogeneously broadened injection laser is presented. The model is based on solutions to differential equations which describe the steady-state amplification of the modes for unidirectional propagation through a homogeneously broadened gain medium. The gain medium is characterized by independently adjustable gain, saturation, and spontaneous- emission profiles f... View full abstract»

    Theory and experiments on optical feedback effects in index-guided single-mode semiconductor lasers are presented. Evidence is found for the existence of a characteristic parameterCwhich indicates the relative strength of the optical feedback. Near the transition (C approx 1.0) from low to high feedback, the feedback-induced low-frequency intensity noise shows a maximum. At h... View full abstract»

    A semiclassical treatment of the time-dependent behavior of a gain-coupled, distributed feedback laser (DFL) has been developed. This treatment takes into account the field propagation within the DFL, and is therefore capable of predicting its behavior even for extremely short pump pulses. Comparisons are made to existing steady-state and transient theories where they are valid, showing good agree... View full abstract»

    An exact analysis, based on local field expansion, is used in order to calculate the coupling coefficient in corrugated waveguide structures having rectangular tooth shape and small tooth height. In particular, the coupling coefficients for TE field polarization and TM field polarization are derived. It is shown that the expression for the TE coupling is identical with previous results based on th... View full abstract»

    Over 300 new submillimeter-wave laser emission lines are predicted for the ν5band of deuterated fluoroform (CDF3) when isotopic CO2and N2O infrared pump lasers are used. These lines are calculated by using recently derived molecular constants that were determined by fitting known infrared, microwave, and submillimeter-wave transitions in CDF3 View full abstract»

    -A discussion of second harmonic generation with imperfect phase matching in the high conversion limit is presented. Phase modulation of the fundamental pulse, dispersion, central frequency wavevector mismatch, and fundamental depletion are included. The results show that even small amounts of phase modulation or central frequency wavevector mismatch can limit harmonic generation and must be consi... View full abstract»

    Techniques of short pulse generation in discharge-pumped excimer lasers are experimentally and analytically investigated around the 1 ns region. With a compact Blumlein-type XeCl laser and an 8 cm cavity length, a lasing pulse duration of 1 ns FWHM was obtained. The pulse duration is remarkably shortened in comparison with the pumping period through the mechanism of controlled resonator transients... View full abstract»

    Short pulse (∼ 2 ns) saturation properties at the XeCl wavelength of the UV dyes polyphenyl, BPBD, and BBQ show evidence of excited state absorption which could not be fully saturated. This may explain the difficulty in achieving very short pulses by passive mode locking of the excimer lasers. No evidence was found of photodessociation of the dye which could cause a long transmission recover... View full abstract»

    In this second paper of a series I present statistical results obtained from computer simulated experiments in single-cavity semiconductor lasers and show that the probability distribution for realistic lasers are much broader than the Poisson distribution. When the gain saturation parameter is properly chosen, the computer simulated probability distributions agree very well with published experim... View full abstract»
