Design of quasi-continuously tunable laser based on filtered feedback for sensing applications using generic building blocks

We present the design of a novel quasi-continuously tunable laser based on the filtered-feedback principle. This laser was specifically designed for use in Fiber Bragg Grating optical sensing applications. It can sweep rapidly over 10 discrete wavelength bands in the 1520-1580 nm wavelength range. The aim is to provide simultaneous wavelength scanning rates of up to 1 MHz. The laser was designed using generic building blocks and is therefore compatible with the future generic foundry infrastructure that is being set-up in Europe
