Eblana Photonics of Dublin, Ireland, a designer and manufacturer of laser diodes for communications and other applications, Whose proprietary laser technology offers narrow emission linewidth of < 400 kHz at low emitted power and bias current, mode hop free wavelength tuning by varying bias current and/or temperature, and wavelength stability. Offering an extensive line of laser products delivering wavelength ranges from 1310 nm to 1550 nm and data rates ranging from 1 Gbit/s to 10 Gbit/s.
Has announced completed development of the EP1550-NLW-B narrow linewidth semiconductor laser product series, designed to complement Eblana's existing product portfolio for applications such as GPON, GEPON, CATV and SONET/SDH, and has begun commercial shipments.
Already being used in high bandwidth coherent communications applications where, for example, high spectral efficiency, phase encoded signals are used to overcome transmission bottlenecks, and in various sensor, medical and imaging applications, the 1550 nm EP1550-NLW-B Series lasers feature: Guaranteed emission line-widths specified at 400 kHz and below. Highly linear Light Current characteristics and high Side Mode Suppression Ratio (SMSR). Industry standard hermetically-sealed, 14-pin butterfly package integrated with optical isolator, thermo-electric cooler, thermistor and power monitor photodiode. Individual test data of the measured linewidth.
James O'Gorman, CEO and founder of Eblana, commented, "A key impact of our technology on the product's performance is that the laser emits in a ultra-narrow line even at low emitted powers unlike DFB lasers which have to be driven at extreme operating points to achieve even MHz line-widths".
