Abstract

Grating structures will be key elements of high density wavelength division multiplexed (WDM) communications systems. A recently developed acrylate photopolymer waveguide technology, referred to as Polyguide,^1,2 has the ability to combine in a single material system both high quality single-mode waveguides³ and thick Bragg grating structures.⁴ We have investigated the performance of microgratings in buried single-mode guides for WDM applications in this polymer system. Gratings are created holographically using an argon-ion laser, with size and position determined by a photolithographic mask. Grating lengths of 25-250 µm have been fabricated in a variety of device structures.
