dc.description.abstract | Analysis and experimental results on a polarization independent electrooptic
matched filter (EMF) with a center wavelength of 1.53 μm are reported. The EMF
utilizes electrooptic phase-matched TE↔TM conversion in a Ti-diffused waveguide on
a LiNbO3 substrate. The operation of the EMF to select an optical frequency channel is
controlled by applying independent voltages to interdigital electrode sets cascaded
along a single mode waveguide. The device is inherently polarization independent and
has the potential for submicrosecond tuning. The number of selectable channels N is
related to the number of electrode sets P by the formula / 2 1 N P = + . A matrix analysis
is used to determine the TE↔TM conversion efficiency for the case that 8 P = and
5 N = . A driving circuit for the EMF was implemented using a digital-to-analog
converter (DAC) array controlled from a personal computer (PC). Transmittance
spectra of a filter produced in a LiNbO3 substrate are presented. A raised cosine
weighting function applied along the 3.8 cm length of an EMF provides a sidelobe
suppression level better than Â17 dB with a 1.0 nm 3-dB bandwidth. | en |
