Abstract :
This paper presents a vertical external cavity surface emitting lasers (VECSEL) system based on 20 compressively-strained GalnP quantum wells (QWs) for an operation wavelength of around 660 nm. In the active region, five QW packages are placed in (Al0.55Ga0.45)0.51In0.49P cladding layers in a resonant periodic gain (RPG) design. With simulations based on the transfer matrix method, the QW packages are placed in the antinodes of the standing wave of the electric field intensity in the active region. The 3-λ cavity is fabricated on a 55λ/4 pairs Al0.50Ga0.50As/AlAs distributed Bragg reflector.
