Paper Abstract

We present a preliminary study of all-optical switching devices based on the photo and electrochromic behavior of sputtered and sol-gel based tungsten oxide films. While many questions remain unanswered these films show considerable promise for meeting a variety of switching applications. These switching applications complement the optical memory applications we have previously demonstrated. In the present study we have used 488 nm control light to switch 632 nm data light. The films range from about 100 nm to 900 nm in thickness and can be deposited on various substrates. The switching was characterized using single layer films. The switching time is currently submillisecond with incident control powers of just a few tens of milliwatts of control light using a spot size of about ten microns in diameter.
