Abstract:
An optical pulse generator, comprising:an optical modulator having a pair of end faces and comprising an optical modulation region operable to modulate light incident on one of said end faces and to output modulated light from the other of said end faces;an optical phase adjuster operable to adjust a phase of the modulated light outputted from the other of said end faces and to output the phase adjusted modulated light back to the other of said end faces; andan optical reflector, wherein said optical phase adjuster is operable to adjust an optical distance between said optical modulator and said optical reflector such that a product of time that the modulated light has taken to propagate from said optical modulator back to said optical modulator after being reflected by said optical reflector and an angular frequency of the modulation light applied on said optical modulator is an odd multiple of a phase corresponding to a half wavelength of the modulation light.
