Tunable 10G TOSA, LambdaFLEX

The Lumentum LambdaFLEX™ Tunable 10 Gbps TOSA is a high-performance tunable laser transmitter incorporating the Lumentum DSDBR wideband tunable laser, monolithically integrated with InP Mach-Zehnder modulator (MZ). With no moving parts, it is a low voltage electronically-tuned device enabling rapid wavelength switching with straightforward control electronics. An integrated semiconductor optical amplifier (SOA) provisions the optical power control and also acts as a shutter to allow dark tuning when reverse biased.

Wavelength control is achieved with the internal wavelength locker in conjunction with an external control scheme which interfaces to the laser via the ASIC. The ASIC allows ease of integration and incorporates a 14 bit, multichannel current output DAC providing an I2C interface to the laser, SOA, and M-Z functions. The device will lock to either a 50 GHz or 100 GHz ITU wavelength grid. Output power monitoring is provided by an integrated tap electrode.

Modulation at up to 11.3 Gbps is applied via differential inputs to the InP Mach-Zehnder modulator. Separate M-Z bias inputs permit precise setting of extinction ratio (ER) and crossing point.
