FiboTEC's Fibolux ECLD is a range of compact Single Frequency Laser Diode Systems based on External Cavity Laser Diodes (ECLDs).
ECLDs are a cost effective coherent laser source supplied in an industry standard butterfly package with TEC, thermistor and monitor photodiode. The use of an external grating for wavelength stabilisation results in a substantially longer coherence length than other semiconductor lasers (including DFBs), and a low phase noise. Sub-MHz linewidth (in cw mode) and wavelength stability are assured by design, eliminating the need for wavelength lockers and complex feedback control circuits.
Wavelengths for the standard systems are in the range 1529nm to 1565nm with typical mode-hop-free tuning of 20GHz and a total tuning range up to 100GHz (0.8nm). The typical output power in the range of 8-15mW may be post-amplified by integrating an EDFA. Wavelength multiplexing and modulation input is also available.
The Fibolux ECLD is used in a variety of applications such as standard and advanced spectroscopy; interferometric instruments (including hydrophones & geophones); LIDAR; optical test & frequency conversion.
