Hybrid Coupling of Laser Light sources to Silicon (Oxy)Nitride Based Waveguides
conference paper
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 (λ = 850 nm) laserdiode was coupled to a SiON based slab waveguide (efficiency η EQ 25 - 30%) and to a Si2N4 based ridge waveguide (efficiency η = 20%) on silicon. A start has been made with the determination of the lifetime of thermocompression mounted laserdiodes. AlGaAs (λ = 850 nm) lasers as well as AlGaInP (λ = 675 nm) lasers were tested. The first results indicate that lifetimes in the range 10 - 30 years are possible for CW operation at 30°C. The laser- waveguide coupling technique is demonstrated in a sensor platform.
