Improved thermal performance is thus expected from the InGaAsN-based lasers. In the work we present a comparative study of the laser characteristics of strain InGa(N)As/GaAs QWs structures grown on a GaAs substrate by atmospheric pressure. Dimethylhydrazine has been used as source of nitrogen for the growth, and the growth conditions (temperature, V/III flux ratio, ratio of DMHB in the gas phase) has been chosen to obtain a mirror like surface and maximum nitrogen incorporation.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.

It is found that the modal gain and the T/sub 0/ value can be increased simultaneously. Three different ways to improve the modal gain and T/sub 0/ value are discussed. Additionally, it is pointed out that the low threshold current density of QD lasers, is due primarily to \"physical scaling\" rather than any quantum effect. The performance tradeoffs occur between the threshold current density and the ground state modal gain and T/sub 0/ value. QD lasers with InAs/In/sub x/Ga/sub 1-x/As dots-in-a-well (DWELL) structure are used.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.

Their functionality could however also be useful in a number of new system concepts that are currently under investigation. For some of these new system concepts, it is relevant to know up to which bit rate the widely tunable laser diodes could be directly modulated. We have studied the direct modulation properties of 3 types of widely tunable laser diodes: the Altitun GCSR laser, the NTT SSG-DBR laser and the Marconi SGDBR laser. Different types of measurements, from parasitic-free RIN measurements to eye-diagram measurements and link experiments, have been carried out. None of the investigated laser designs however was particularly optimised for high-speed operation. From the RIN measurements, the K-factor and the theoretical maximum modulation frequency under small-signal modulation have been derived. For all investigated lasers and for typically 40 to 50 channels with a spacing of 100 GHz, the theoretical maximum modulation frequency was always found to be close to and generally over 10 GHz.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.
