ABSTRACT
Work on single-frequency tunable-wavelength semiconductor lasers with an external cavity based on fiber Bragg gratings formed in a single-mode optical fiber is reported. Methods for discrete and continuous tuning of the emission wavelength are considered. The described lasers emit dynamically stable radiation with a narrow linewidth (10 kHz) in the wavelength range of 635-1650 nm.

    A novel dispersion-compensating fiber Bragg grating (FBG)-based en/decoder is proposed to compensate both the out-band and in-band dispersion in a time-spreading/wavelength-hopping (TS/WH) optical code-division multiplexing (OCDM) system. The experimental realization of such en/decoders only...
