In general, stress can create about the same change in the mdcx of refraction of an optical modulator as can a thermaloptic approach, but with a faster response, a smaller, simpler configuration and with less power needed to operate. Also, S-O's creates a greater change in the index than do other fields that are commonly used for modulation, such as with Electro-Optic's. The Stress—Optic technique is also durable. A 2 x 2 switch has been in operation at SeaLite Engineering since 1991; it has 1O'S cycles at 1 KHz. To implement this technology SeaLite Engineering is developing a Stress-Optic guided wave switch and technique as an add-on to a photonic integrated circuit substrate. Stress-Optic beam switching within a photomc integrated circuit can be fabricated in a nearly automated process where the S-O films are applied during the assembly of the planar waveguides. The S-O technique is fast (kHz to MHz, depending upon the circuit dimensions), low power (10's ofmicrowatts per cycle) and rugged (< lO"8cycles to date).
