Micro-ITLA Tunable Laser, 300 kHz Linewidth, LambdaFLEX

The Lumentum LambdaFLEX™ micro-ITLA is a high performance, narrow linewidth, continuous wave (CW), tunable laser source designed for 100G/200G coherent modules and linecards. The micro-ITLA features high output power, a small form factor, and low power dissipation specifically designed to meet the needs of next generation coherent applications. The DS-DBR laser is based on 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 laser and control electronics are pre-mounted on a dedicated circuit board for easy production installation. The micro-ITLA features shuttered tuning, optical power control, off-grid tuning, and narrow linewidth. Comprehensive control and system reporting is provided over the RS232 interface.

The micro-ITLA incorporates the Lumentum DS-DBR wideband tunable laser. 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 stabilized temperature with off-grid tuning implemented thermally to achieve ±9 GHz un-shuttered fine tuning. Wavelength stability is guaranteed by an internal wavelength locker for control. Facet output power monitoring is also provided by an integral photodiode.

The device is provided with polarization-maintaining fiber for use with an external modulator.

The product is offered in both a micro-ITLA format ((TL5300/TL5350) and a dual-ITLA format (TL5370). The dual-ITLA format contains two fully independent lasers through one electrical interface, offering a significant footprint reduction.
