Abstract

Commercially available polyimides (PI) have been evaluated in the form of a 20 X 20 micrometers waveguide on a silicon substrate with 6 micrometers quartz as undercladding. A Fabry- Perot laser diode (LD) has been aligned to the waveguide. Silicone elastomere (SiR) has been multi-purposely used for overcladding of the waveguide, for indexmatching between the waveguide and LD and for encapsulation of the LD. The optical characterization of the whole device has included measurements of optical output power as a function of drive current, and threshold current as a function of time. No statistically significant increase of threshold current has been noticed during the test period. It is shown that the optical loss spectrum of the waveguide over the wavelength interval of 0.6 - 1.6 micrometers is strongly dependent on the curing parameters of the PI.
