Latest Patents

One of his latest patents is an optical interleaver. This invention comprises a first optical 3×3 coupler that receives a broadband optical signal at one input port. It also includes a second 3×3 optical coupler and three differential delay lines connected in parallel between the output ports of the first coupler and the input ports of the second coupler. Additionally, an infinite impulse response (IIR) element is disposed in each of two delay lines. The optical signals traveling in the respective delay lines interfere at the second coupler, producing three frequency-shifted transmission channel output signals at the respective output ports. Another notable patent is an equalizer circuit for a light source. This optical equalizer circuit consists of M optical couplers linked by differential delay lines. The coupling ratios for the respective M optical couplers are calculated based on an input signal from the light source and a designed profile that the optical input is to be equalized to.
