Popis:	The propagation loss of optical waveguides index imaged in a 0.5 μm poly(cyclohexylsilyne) (PCHS) film through photo‐oxidative cross linking with ultraviolet exposure at 310 nm is measured and compared to an experimental estimate of PCHS bulk propagation loss. Measured waveguide losses at 632.8 nm range from 0.6 dB/cm for TE operation of 2‐μm‐wide PCHS waveguides to 2.1 dB/cm for TM operated 4‐μm‐wide guides. Comparison to the bulk PCHS propagation loss estimate of 0.04 dB/cm at 632.8 nm indicates a significant increase in loss upon thin film waveguide fabrication.
