Abstract
A 2-bit (four delays) polymer waveguide delay device is demonstrated and characterized. The device is composed of polymer waveguide delay lines, optical fiber delay lines, and polymer thermooptical 2/spl times/2 switches. The insertion loss for the fully integrated device ranges between 8.12 and 9.81 dB depending on the delay path chosen. The polarization-dependant loss is 0.04 dB. Measured delays are 0, 37.8, 160.4, and 199.2 ps. The switching speed is less than 4 ms. The designed polymer waveguide delays match well with the measured values.Keywords
