Abstract :
Summary form only given. Over the last years tunable lasers have been developed rapidly due to the advantage they can provide for WDM systems. Traditional 1:1 protection of the systems requires a spare optical transceiver for each working one. Tunable transceivers can reduce total system cost by providing 1:N protection with one tunable transceiver acting as a backup for N working transceivers. At the same time, fast tunable lasers can improve QoS by permitting dynamic wavelength allocation. The two-section DBR (distributed Bragg reflector) laser diode chip is discretely tuned between 7 wavelengths with a nominal channel spacing of 100 GHz over a 5.2 nm range.
