Description
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
L
--
wavelengths λ is n = 2 × . If L >> λ then we speak of a Fabry-Perot Laser because the
λ
laserdiode emits multi-longitudinal modes. Typically the laserdiode is 250 µm long. For
λ = 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 L which is in the range
of λ. For such a reduced oscillator length the standing wavelength condition will be
fulfilled for n ≈ 2 what means for only one wavelength.

The tracking error TE is the maximum deviation of PF at constant current Imon over a specified temperature
range and relative to the reference point: Imon, ref = Imon (T = 25°C, PF = 0.5 PF, max.). Thus, TE is given by:
