摘要： A method of reducing undulation in the L vs. I curve of a laser which uses a fiber grating is presented. The spectral width of the fiber grating is made larger than the Fabry-Perot spacing of the laser cavity. As a result, as the laser shifts between harmonics due to laser functioning (e.g., laser drive current, laser aging, temperature change, or mechanical stress), the fiber grating is able to respond linearly because of a large spectral width.

摘要： A semiconductor laser having a single transverse mode operation. Optical power higher than that generated by conventional pump lasers is achieved by widening the gain medium without inducing the second transverse mode. This is accomplished by providing a small refractive index difference between active and blocking regions of the laser. The refractive index difference between the laser active region material and the laser blocking region material at the fundamental frequency is less than about 0.029.

摘要： Semiconductor lasers are susceptible to harmful high currents or high voltage electrical transients. Semiconductor pump lasers are especially vulnerable to electrical transients under normal operation because of the large continuous wave current needed to drive the semiconductor pump laser to achieve a high optical power. A protection circuit for 980 nm pump lasers using a non-linear voltage-dependent resistance means which limits drive current based on a drive voltage powering a laser diode is demonstrated to be effective in guarding the laser against harmful electrical transients.

摘要： The present invention is directed to a large area single-mode (LASM) laser system that provides a laser having a wider gain region and thus a higher power output without introducing the second transverse mode into the optical signal. The laser system of the present invention also reduces the laser junction temperature, thereby improving the reliability of the laser and of laser systems constructed therefrom. The present invention also provides a stabilized spectrum in an optical signal by providing a means for feeding back from an external fiber grating to the laser only a single mode and a selective spectrum of an optical signal generated by the laser.

摘要： A lens system for use with elliptical optical sources includes a spherical fiber lens disposed beyond a conventional confocal lens arrangement. The spherical fiber lens is disposed in the optical path at the point where the slow axis (X ray) crosses the fast axis (Y ray); the rays will be "circular" and will thereafter propagate as a circular wavefront. The coupling efficiency of such a system is thus improved from approximately 40% to over 80%. The radius of the spherical endface of the fiber lens may be adjusted to improve the coupling efficiency. The spherical fiber lens is easily formed by fusing a section of "coreless" silica fiber onto the endface of a conventional single mode fiber. The end of the silica fiber is thereafter prepared (by heating, etching, polishing, or laser machining, for example) to provide a spherical endface with the desired radius.

摘要： The invention is a semiconductor optical device and method of fabrication where the device includes an active region with an active layer having a first index of refraction, and a blocking region having a second, lower index of refraction. A semiconductor layer having an index of refraction higher than the blocking region is formed over both the active and blocking regions so that the semiconductor layer is in closer proximity to the active layer in areas not covered by the blocking region so as to decrease the difference between the effective index of refraction in the active region and the effective refractive index of the blocking region. Such devices are particularly useful for pumping optical amplifiers since greater power can be achieved while maintaining single mode emission.
