    Abstract: A laser diode apparatus including a diode laser, optics efficiently collimate the diode laser beam, and a narrow band reflector to provide optical feedback for wavelength stabilization of the diode laser in an extended cavity configuration. The extended cavity laser diode assembly has a low reflectivity coating applied to the front facet, and a narrow-band reflectivity engineered to optimize the output power from the diode laser, leading to power penalty-free operation of the extended cavity laser diode assembly as compared to a free-running diode laser. The extended cavity laser diode assembly can equally applied to a plurality of laser diodes, with either a single or a plurality of optical feedback devices forming the extended cavity configuration.

    Abstract: The invention relates to optical system including light sources that amplify light using a gain medium. Systems and method of the invention are provided for amplifying light while inhibiting reflections at a peak gain of the gain medium, thereby suppressing parasitic lasing. This allows a system to use a broad range of wavelengths without parasitic lasing, thereby increasing the useable range of a tunable optical filter. In this manner, light at wavelengths not at a peak gain can be used effectively, and the gain medium of an optical amplifier does not limit use of a system to a narrow range of wavelengths associated with a peak gain of the gain medium. A single optical system according to the invention can thus be used for applications that require a broad range of wavelengths.

    Abstract: Two or more lasers or other temperature sensitive optical devices can be disposed in an operating environment, for example in a common enclosure exposed to the environment. The environment can have a temperature that fluctuates, for example in connection with random events, weather, seasons, etc. Each laser's temperature can track the temperature of the environment in steps, with each laser following a distinct temperature track. The lasers can alternate outputting light into a wavelength division multiplexing channel. For example, during one timeframe, one laser can provide an optical communication signal having a wavelength complying with a wavelength division multiplexing criterion. During another timeframe, the other laser can provide an optical signal having substantially the same wavelength. Operating a laser at an elevated temperature can shorten laser lifetime. To mitigate temperature induced failure, a replacement laser can be engaged when a failure predictor, precursor, or indicator meets a threshold.
