Product Description - Tunable Laser (iTLA)

The Optoplex TL-MC040TA101 tunable laser is a high performance continuous wave (CW) tunable laser source for various test and measurement applications the C-band wavelength range covering from 1528nm (196.25 THz) to 1568nm (191.25 THz).

This tunable laser source is based on the OIF micro-iTLA standard. The laser and control electronics are pre-mounted on a dedicated circuit board for easy production installation. The tunable laser is featuring shuttered tuning, optical power control, off-grid tuning, adjustable grid spacing and narrow linewidth. A Labview software program and an RS232/USB cable are provided together with the tunable laser module. Users can plus and play with a computer (PC) to control the tunable laser very conveniently.

The TL-MC040TA101 tunable laser designed on a fully monolithic InP chip without moving parts, it is a low voltage electronically tuned device enabling channel 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 tuning is implemented with thermal control. It can be tuned on grid or off-grid with a minimum tuning step of 0.1GHz. When operated in ON-Grid tuning, the tuning is shuttered. While in fine-tuning (+/-9GHz) mode, it is un-shuttered operation.

The TL-MC040TA101 tunable laser has a wavelength accuracy about 3.5pm max and a power stability of 0.02dB max (both measured in a period of 60 minutes).

With accurate wavelength and stable power output, the laser is ideal for many test and measurement applications, optical component and material characterization, and optical monitoring applications such as optical monitoring in optical thin film coating.
