TL5000VCJ Integrable Tunable Laser Assembly with
variable output power
Issue 1 January 2007
The Bookham LambdaFLEX^TM iTLA is a high performance
continuous wave (CW) tunable laser source for use in the
C-band window covering 1528nm to 1563nm. 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.
