Claim Text:
1. An optical signal conversion device, comprising: an optical input, wherein the optical input is an optical double-sideband modulation signal, and wherein the optical double-sideband modulation signal is a microwave-modulated optical signal with two microwave modulation sidebands of equal power; an optical output, wherein the optical output is an optical single-sideband modulation signal, and wherein the optical single-sideband modulation signal is a microwave-modulated optical signal with two microwave modulation sidebands of unequal power; and an optical signal conversion module comprising a semiconductor laser to convert the optical input into the optical output using period-one nonlinear dynamics of the semiconductor laser, wherein the optical input falls within the domain for conversion from optical double-sideband modulation signals to optical single-sideband modulation signals using the period-one nonlinear dynamics of the semiconductor laser, wherein a microwave modulation frequency of the optical input falls within a certain range of a few tens of gigahertz around an oscillation frequency of the period-one nonlinear dynamics, wherein the certain range depends on the power of the microwave modulation sidebands of the optical input.
