Refractive index control of benzocyclobutene (BCB 402440) is achieved by facilitating different conditions during the thermal curing of BCB film. Refractive index (RI) change of 1.49 is obtained with curing of BCB film using an oven, while the RI change is 0.1 when the BCB is cured using a hotplate. The two different curing methods exhibit a temperature dependent refractive index change of the BCB photosensitive polymer. By carefully controlling the curing conditions, multiple layers of BCB with different RI can be fabricated, which can then be applied in the fabrication of optical waveguides.
