WebGain chips are semiconductor optical elements used as the optical gain medium of external cavity laser diodes. Gain chips are used as a TLS (Tunable Light Source) that can change the oscillation wavelength using a wavelength selection filter such as a diffraction grating. Example schematic of Littrow arrangement type external cavity laser WebGain is maximumwhen = o (i.e. the gain coefficient is at resonance). At non-resonant frequencies the gain follows the homogeneously broadened characteristics of a two level atom(i.e. Lorentzian profile). The gain BWfor this spectrum is typically expressed as the (Full Width at Half Maximum) FWHM g2T2. 2 g g with Tp20.1s g3THz how are redundancies calculated
