Palladium coated edge-emitting lasers for hydrogen sensing applications
… film of palladium deposited on the ridge of an edge-emitting laser has been designed and fabricated. This palladium film is well known to react to hydrogen, forming palladium hydride with optical properties dependent on the hydrogen concentration. This reaction yields a change in complex …

Self-heating control of edge emitting and vertical cavity surface emitting lasers
Self-heating leads to temperature rise of laser diode and limits the output power, efficiency and modulation bandwidth due to increased loss and decreased differential gain. The main heat sources in laser diode during continuous wave operation are Joule heating and free carrier absorption loss. To …
