We have developed a 2 by 2 digital optical switch (DOS) composed of four 1 by 2 DOS elements and a thermo-optic wavelength tunable filter using silicone resin waveguides. The 2 by 2 DOS operated with a switching power of 380 mW, a very low crosstalk of less than -60 dB, and a low insertion loss of less than 2.5 dB at 1.55 micrometers . The tunable filter operated with a maximum power of 2.5 W, a tuning range of > 30 nm, a crosstalk of < -30 dB, and response time of < 60 ms. We also applied our polymer tunable filter to a WDM/SCM LAN system to confirm its practicality.
