Polarization-bistable VCSELs and their applications for all-optical signal processing

Optical injection and mode-coupling effects in two-color lasers

“…When combined with optical injection, multi-wavelength lasers can function as low-noise THz sources 10 or even enable all-optical THz signal processing 11 and all-optical memory 12,13 . Optical injection, however, leads to complex dynamics, whereby the additional wavelength adds a new degree of freedom and new features [14][15][16] .…”
