Comb-locked telecom-grade tunable laser using a low-cost FPGA-based lockbox

We frequency locked a commercial ITLA (integrable-tunable-laser-assembly) laser to an optical frequency comb with arbitrary carrier frequency within the telecom L band (1570-1625 nm). We achieved long-term...

Compact and low-power comb-locked transmitter based on ITLA tuneable lasers

We suggest and demonstrate a radically new approach to generate frequency-locked optical carriers. It provides for a lowpower- consumption, self-starting and stable fibre comb operating across the entire C-band. We phase lo...
