摘要： A hybrid external cavity laser and a method for configuring the laser having a stabilized wavelength is disclosed. The laser comprises a semiconductor gain section and a volume Bragg grating, wherein a laser emission from the semiconductor gain section is based on a combination of a reflectivity of a front facet of the semiconductor gain section and a reflectivity of the volume Bragg grating and the reflectivity of the semiconductor gain section and the volume Bragg grating are insufficient by themselves to support the laser emission. The hybrid cavity laser further comprises an etalon that provides further wavelength stability.

摘要： A hybrid external cavity laser (HECL) system comprises a diode laser, collection and collimation optics, and a volume Bragg grating, emits radiation at a single wavelength with a short-term wavelength stability in the order of at least one part in a billion The wavelength stability is achieved by use of a thermal management system, comprising inner and outer housings, each containing a temperature sensor, and electronic circuitry that monitors the temperatures and controls both the laser diode current and a thermoelectric cooler based on temperatures determined from said temperature sensors. The laser system is packaged in a compact enclosure that minimizes waste heat, facilitating use in applications that have heretofore employed stable, single-frequency lasers, including He—Ne lasers.

摘要： Disclosed are systems and methods for using a semiconductor optical amplifier (SOA) as an optical modulator for pulsed signals. In accordance with the principles of the invention, the SOA can be biased with a negative voltage to suppress transmission and improve modulator extinction and biased with a positive pulsed signal with sufficient amplitude to forward bias the amplifier (SOA), both transmitting the carrier and increasing its amplitude by means of a gain provided by the SOA under forward biased conditions. In addition, the forward bias voltage may be selected to compensate for losses within the SOA.
