摘要
Rib-type structures formed by layers of polyimides and polyimide-silica hybrid materials with better thermal stability and mechanical strength in polymer materials were presented. Polyimides and polyimide-silica hybrid arrayed waveguide grating (AWG) devices indicated the insertion loss to be -3.12 dB and -3.16 dB. Optical measurements of polyimides and polyimide-silica hybrid materials formed on quartz glass indicated the refractive indexes of top cladding/core/bottom cladding layers at 1550 nm wavelength were 1.522/1.546/1.522 and 1.4907/1.53/1.4907. The extinction of coefficients of all samples exhibited zero at 1550 nm wavelength.
