Abstract
A compact micro-integrated narrow-linewidth extended cavity diode laser (ECDL) based on a volume holographic Bragg grating (VHBG) around 780nm is demonstrated. The ECDL consists of gain chip, micro-optical lenses, VHBG, optical isolator and thermistor. All components are integrated on a AlN ceramic plate, which is on the top of a thermoelectric cooler (TEC). Moveable parts are strictly omitted to provide excellent mechanical stability. The ECDL provides a short-time linewidth(20us) of 70 kHz with 30mW optical power. The mode-hop free range of the ECDL is up to 9GHz. The laser frequency variation is ±1MHz in 40min. The ECDL also has the advantage of the compactness of a standard 14-pin butterfly package with a footprint only 30 mm×12.7 mm.
