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 12):
The method of  claim 11  wherein:\n the dry etch continues to etch the substrate after the elongated spherical photoresist features are completely eroded; and \n the convex curved groove sidewalls of the \u03b3 groove become steeper.
