Abstract

We developed a flat passband acoustooptic filter. For the passband flattening, cascaded bandpass and notch filters with different mode converter lengths and conversion strengths were used. We attained a flat passband with flatness of less than 1 dB in the 2 nm range using the device with a second- to first-stage mode converter length ratio of 1.2.
