Abstract:
1. A device comprising: a first band-pass filter operable to receive a first optical signal from a laser and to transmit a first portion of the first optical signal; and a second band-pass filter operable to receive the first portion of the first optical signal and to transmit a second portion of the first optical signal, wherein said first band-pass filter has a first corner-pass wavelength of λ wherein said second band-pass filter has a second corner-pass wavelength of λ wherein λ wherein is the magnitude of each of the filter pass-band slopes of said first and second band-pass filters, wherein λ wherein CSO wherein CSO wherein N wherein c is the speed of light in a vacuum, wherein m is an optical modulation index 0<m≦1, wherein α is a laser chirp of said laser, wherein y is a laser slope efficiency y of said laser, wherein I is a bias current of said laser, wherein I wherein P wherein the magnitude of each filter pass-band slope of each said first and second band-pass filters satisfies at least one of
