stm51007x description data sheet 3 2001-06-01 description differences between a fabry-perot and a dfb laserdiode a conventional laser consists of an amplifying medium and two end mirrors. the cavity is longer than one wavelength, and a standing wave is created. the number n of half wavelengths is . if l >> then we speak of a fabry-perot laser because the laserdiode emits multi-longitudinal modes. typically the laserdiode is 250 m long. for = 1310 nm/1550 nm n is about 350. therefore for many neighboring wavelengths the ?standing wavelength? condition specified above is fulfilled. for a dfb-laser a special grating acts as a distributed filter allowing only one of the cavity?s longitudinal modes to propagate. this can be described with a reduced oscillator length which is in the range of . for such a reduced oscillator length the standing wavelength condition will be fulfilled for n 2 what means for only one wavelength. figure 2 fabry-perot laserdiode n2 l -- - = l ? 1 wavelength intensity 0 012345 4
