Photonics

Optical network solutions provider II-VI plans to expand the capacity of its 980-nm pump laser production lines, including wafer fabrication and chip-on-carrier assembly in Zürich, Switzerland, and Calamba, Philippines, and pump laser module assembly in Shenzhen, China. II-VI will increase its production capacity to meet the strong demand for data center interconnects and the growing demand for reconfigurable optical add-drop multiplexers (ROADM). This new production capacity is expected to be operational by the end of the calendar year.

A silicon chip that distributes optical signals precisely across a miniature grid could lead to a novel design for neural networks. A research team from the National Institute of Standards and Technology (NIST) proposes to use light, rather than conventional electronics, as a signaling medium for artificial neural networks. The use of light would eliminate interference due to electrical charge, and the light signals would travel faster and farther.

A chip-based device measuring just 1 sq mm has demonstrated the potential to generate quantum-based random numbers at gigabit (Gb)-per-second speeds, using minimal power. The tiny device, which is enabled by silicon photonics, could be used as a stand-alone or in devices such as laptops and smartphones to encrypt data in real time.

Using a 3D printer, a research team at the UCLA Samueli School of Engineering has created an artificial neural network that can analyze large volumes of data and identify objects at the speed of light. Called a diffractive deep neural network (D2NN), the technology uses the light scattering from an object to identify it. The technology is based on a deep learning-based design of passive diffractive layers that work collectively.

Network operators will spend $75 billion optical transport systems over the next five years, predicts the Dell’Oro Group. The market research firm adds in its most recent “Optical Transport 5-Year Forecast Report” that the spending spree will see the market hit $16 billion by 2022. As much as 95% of the money spent on optical network equipment during the time frame will go toward WDM systems, Dell’Oro researchers predict.
