II-VI unveils 980 nm Pump Laser Module for Amplification in High-bit-rate Transceivers

II‐VI Incorporated of Pittsburgh, Pennsylvania USA, introduced an uncooled 980 nm pump laser module that comes in a compact 3-pin micro-format package. II-VI says it designed the new pump laser module to meet the stringent power-efficiency and reliability requirements for ultra-compact amplification systems in both current and next generation high bit-rate transceivers.

“The demand for 100G and 200G coherent transceiver modules will grow in volume at a 21% CAGR from 2016 to 2021,” said Kevin Lefebvre, Principal Analyst for Optical Components, Ovum. “The market expansion for both coherent and PAM4 technologies will be assisted through smaller, more efficient and lower power devices such as II-VI’s uncooled micro-pump laser module.”

II-VI’s MLU96Z-series measures just 141 cubic millimeters in volume. The pump laser has an 80-micron small-bend radius polarization-maintaining fiber pigtail for optical amplification within small transceiver packages.

At its typical use conditions and up to an 80 °C maximum operating temperature, the MLU96Z-series consumes less than 0.5 Watts. The device meets the power consumption requirements of pluggable transceivers.

Dr. Sanjai Parthasarathi, Vice President, Product Marketing and Strategy, Optical Communications Group commented, “Compared to our highly successful 8-pin uncooled mini-DIL pump laser, our new 3-pin micro-pump is 75% smaller and achieves a new breakthrough in 980 nm pump miniaturization.”

The company built the MLU96Z-series its field-proven OC-2 fiber alignment platform. The pump laser relies on II-VI’s G08 laser chip technology to ensure what the company describes as superior stability, reliability, and wavelength locking performance.

II-VI claims that the MLU96Z-series, together with its portfolio of ultra-compact hybrid passives that use its micro-optics technology, enable high-power and low-noise optical amplification within transceiver form-factors that was previously unachievable. Prototype samples of the MLU96Z-series are available now and are expected to be fully qualified in CYQ2 2017.
