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.
