Interband Cascade (IC) Optical Frequency Combs
Abstract
We demonstrate an electrically-driven frequency comb whose sub-picosecond pulses span more than 1 THz of spectral bandwidth centered near 3.6 µm. This is achieved by passively mode locking an interband cascade laser with gain and saturable absorber sections monolithically integrated on the same chip.
