Fiber grating optical spectrum analyzer tap

We demonstrate the first optical spectrum analyzer using a blazed and chirped fiber Bragg grating as the only wavelength dispersive element. A detector array demonstrates 14 nm bandwidth, 0.12 nm resolution, 35 dB dynamic range, and insertion loss less than 1 dB.
