Paper Abstract

An efficient method was developed to couple a diode laser to a high contrast waveguides. The laserdiodes were mounted with sub-micron precision using a thermocompression mounting technique. An AlGaAs ((lambda) equals 850 nm) laserdiode was coupled to a SiON based slab waveguide (efficiency (eta) EQ 25 - 30%) and to a Si2N4 based ridge waveguide (efficiency (eta) equals 20%) on silicon. A start has been made with the determination of the lifetime of thermocompression mounted laserdiodes. AlGaAs ((lambda) equals 850 nm) lasers as well as AlGaInP ((lambda) equals 675 nm) lasers were tested. The first results indicate that lifetimes in the range 10 - 30 years are possible for CW operation at 30 degree(s)C. The laser- waveguide coupling technique is demonstrated in a sensor platform.
