Abstract:
A non-degenerate four-wave mixing (ND-FWM) apparatus comprisinga microcavity including one or more semiconductor quantum wells; an optical signal source for providing an optical pump signal, having a wavelength &ohgr;p and a wave vector kp, injected at a first predetermined oblique angle into the microcavity; an optical probe signal, having a wavelength &ohgr;PR and a predefined wave vector kPR, injected at a second predetermined oblique angle into the microcavity; and an output signal generated in said microcavity from said pump and said probe, said output signal exiting the microcavity at an oblique angle and having a wavelength of 2&ohgr;Pâˆ’&ohgr;PR and a wave vector equal to 2kPâˆ’kPR.
