TL5000VLJ

The Bookham LambdaFLEX^TM iTLA is a high performance continuous wave (CW) tunable laser source for use in the L-band window covering 1568nm to 1607nm. The DSDBR laser source and control electronics are populated onto a circuit board assembly and mechanical interface. The iTLA features variable power, shuttered tuning, trace tone and SBS dither circuitry. Comprehensive control and system reporting is provided over the RS232 interface.

The iTLA implements the Bookham DSDBR wideband tunable laser. This laser is a fully monolithic InP chip designed for high volume, low cost manufacturing. With no moving parts, it is a low voltage electronically tuned device enabling rapid wavelength switching via straightforward control electronics. The integrated semiconductor optical amplifier (SOA) provisions the optical power control and also acts as a shutter to allow dark tuning when reverse biased.

The laser chip is operated at a fixed temperature, thereby eliminating any slow speed wavelength drift during tuning. Wavelength stability is guaranteed by an internal wavelength locker providing control to a 50GHz or 100GHz ITU wavelength grid. Front facet output power monitoring is also provided by the wavelength locker for feedback control to the SOA. The device is supplied with polarization maintaining fibre for use with an external modulator.
