  • Tunics T100R O-Band Laser

LANNION, France, March 11, 2011 — Yenista Optics has released a tunable laser in the 1310-nm-wavelength region. The Tunics T100R model uses a new optical cavity design to provide optical power of 6 dBm with low-noise >80 dB/0.1-nm signal-to-spontaneous-emission ratio.

Patented self-filtered external cavity laser technology enables the combination of low noise and high power. The O-band laser operates from 1270 to 1340 nm and is suitable for characterizing narrow-bandwidth filters and for functioning as a light source for testing high-speed transmission systems. Engineers developing and testing components for the latest 40- and 100-Gigabit Ethernet and fiber-to-the-home/passive optical networks benefit from the performance of this laser, according to the company. Proprietary Optim-Y technology delivers high wavelength accuracy and mode-hop-free operation with no amplified spontaneous emission.

The laser operates in both sweeping and step-by-step modes, has a wide tuning range from 1490 to 1650 nm, and includes an integrated wavelength meter that delivers absolute wavelength accuracy of ±5 pm and stability down to ±1 pm/h.

Applications include coarse and dense wavelength division multiplexing channel simulation, optical components testing (couplers, splitters, filters, fiber Bragg gratings, reconfigurable optical add/drop multiplexers), erbium-doped fiber amplifer and optical amplifier testing, tunable laser probes for high-end loss or dispersion measurement, spectroscopy, and long-term monitoring of thin-film growth and in-process alignment.

Typical tuning repeatability is ±1 pm, wavelength setting resolution is 1 pm, optical frequency fine tuning is ±2 GHz, return loss is 60 dB, and operating temperature is from 18 to 35 °C.

light source
The generic term applied to all sources of visible radiation from burning matter to ionized vapors and lasers, regardless of the degree of excitation.
tunable laser
Any form of laser; e.g., a dye laser, having an output that can be adjusted over a wide range of wavelengths. Normally the range is about 70 nm wide.
wavelength meter
A device that measures the wavelength of an electromagnetic wave.
