Abstract:
Devices with gamma (γ) grooves are disclosed. The γ grooves can be used to form optical fiber arrays. The γ grooves can be formed using a dry etch, such as RIE, by modifying resist features of an etch mask to have convex curved sidewalls. The profile of the resist features is transferred to the substrate by the dry etch to form the γ grooves. The γ grooves are formed without K containing etchants, avoiding K +  ions contamination of process tools as well as health issues caused by handling alkali containing devices.

Claim (Index 22):
The method of  claim 21  wherein:\n forming the patterned photoresist etch mask forms an array of elongated photoresist features separated by spaces, wherein the elongated photoresist features comprise convex curved photoresist sidewalls; and \n performing the dry etch forms an array of \u03b3 grooves in the substrate in the spaces between the elongated photoresist features, wherein the \u03b3 grooves comprise convex curved groove sidewalls.
