Abstract

To investigate physical mechanisms involved in longterm wavelength drift of tunable distributed Bragg reflector (DBR) laser, the evolution of the tuning characteristics as well as the Bragg section intensity modulation response of several DBR lasers have been simultaneously assessed by current injection in the Bragg section only. Current versus voltage I(V) characteristics under aging have also been recorded to compare the role of leakage current and nonradiative recombination defect evolution, The wavelength drift as well as the carrier lifetime, of the tuning section vary following an exponential law A + B exp(-t(A)/tau) versus aging time t(A). The time constant tau is aging temperature and Bragg current dependant. The carrier lifetime decreases with time indicating a wavelength drift mainly due to nonradiativerecombination defect increase. Modeling of the I-B(V) and lambda B(I-B) characteristics is presented, that fits nicely the experimental data. The exponential form of the wavelength drift is used to propose novel and adequateburning conditions of DBR lasers.
