Abstract:
An optical interference modulator comprises a main input, a main output, an optical splitter connected to the main input, first and second MMI couplers, each with a first primary-end access port connected to the splitter; a second primary-end access port connected to the main output; a first secondary-end access port connected to a respective primary wave-guide; and a second secondary-end access port connected to a respective secondary wave-guide. A light reflector is arranged to reflect light incident from said primary and secondary waveguides back into the same respective waveguide such that light travelling through the respective waveguide from the respective secondary-end access port, after reflection, travels back to the same secondary-end access port. For the MMI couplers, at least one of the respective primary and secondary waveguides comprises a respective light phase modulating device arranged to modulate the phase of light travelling along the corresponding waveguide in either direction.

Claim (Index 1):
Optical interference modulator, comprising\n a main input for light to be modulated, a main output for modulated light, an optical splitter connected to the main input, respective first and second MMI (MultiMode Interference) couplers, each with\n a respective first primary-end access port connected to the splitter; \n a respective second primary-end access port connected to the main output; \n a respective first secondary-end access port connected to a respective primary waveguide; and \n a respective second secondary-end access port connected to a respective secondary waveguide, \n wherein the modulator further comprises a light reflector arranged to reflect light incident from said primary and secondary waveguides back into the same respective waveguide, so that light travelling through the waveguide in question from said respective first or second MMI coupler secondary-end access port will, after reflection, travel back to the same first or second MMI coupler secondary-end access port, wherein, for both the first and second MMI couplers, at least one of the said respective primary and secondary waveguides comprises a respective light phase modulating device arranged to modulate the phase of light travelling along the waveguide in question in both directions; and wherein both the first and second MMI couplers are arranged so that a different respective phase shift is imparted to light travelling between a primary-end access port and a secondary-end access port in a cross state as compared to in a bar state.
