Abstract:
A multiwavelength actively mode-locked external cavity semiconductor (MWML) laser, said MWML laser comprising:at least one optical gain module comprising a semiconductor optical amplifier (SOA) disposed in said cavity which is biased by a radio frequency signal having a frequency that substantially equals the rate at which optical pulses circulate within the cavity, said SOA being mounted in a hermetically-sealed package and simultaneously outputting at a port of said SOA periodic pulses at a plurality of wavelengths;at least one of feedback and feedthrough modules coupled to said port of said SOA so as to provide substantially identical round-trip travel times within said cavity for pulses at said plurality of wavelengths and net gains which are substantially equal at each generated wavelength.
