Data Sheet

1

continuous wave (CW) tunable laser source for use in the L-band

window covering 1568nm to 1607nm. Based on the OIF iTLA

standard, the laser and control electronics are pre-mounted on

a dedicated circuit board for easy production installation. The

iTLA features 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 with 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.

Laser chip operation is at a fixed temperature. Wavelength

stability is guaranteed by an internal wavelength locker for

control to a 50GHz or 100GHz ITU wavelength grid. Front facet

output power monitoring is also provided by the wavelength

locker for feedback control through the SOA. The

device

is

provided with polarization maintaining fibre for use with an

external modulator.
