In this work, a monolithic Y-branch laser diode is used for continuous wave Terahertz generation and detection. The output of the laser diode is fiber coupled, amplified and fed into a photoconductor based cw Terahertz setup. While this system can be

The NIR/MIR region between 1.8μm and 3.5μm contains important absorption lines for gas detection. State of the art are InP laser based setups, which show poor gain above 1.8μm and cannot be applied beyond 2.1μm. GaSb laser show a significantly hi
