NeoPhotonics to demo new technologies for next-gen telecom and data-center networks at OFC

At the Optical Networking and Communication Conference & Exhibition (OFC 2019) in San Diego (5-7 March), NeoPhotonics Corp of San Jose, CA, USA (a vertically integrated designer and manufacturer of hybrid photonic integrated optoelectronic modules and subsystems for high-speed communications networks) is demonstrating several of its new technologies, including a silicon photonics-based 64Gbaud coherent optical sub-assembly (COSA). Additionally, it will demonstrate its silicon photonics-based ultra-narrow-linewidth Pico Tunable Laser and a single-chip array of tunable optical filters, both of which can be integrated with other photonic integrated circuits (PICs) or separately packaged. Finally, it is demonstrating its new CFP2-DCO pluggable coherent module.

NeoPhotonics’ Class 40, 64Gbaud, silicon photonics-based COSA contains a coherent I/Q modulator and coherent receiver fabricated using silicon photonics and based on NeoPhotonics designs. The PIC is designed for low V-Pi, low insertion loss and a high extinction ratio and is co-packaged with drivers and trans-impedance amplifiers (TIAs). The COSA is about half the size of the existing discrete component solution.
NeoPhotonics’ silicon photonics-based Pico Tunable Laser utilizes the same unique, high-performance external-cavity architecture as its Micro-ITLA and just introduced Nano-ITLA product line, but with key optical elements integrated within a silicon photonics chip. The Pico-Laser is designed to exhibit comparable performance to the currently shipping Micro- and Nano-ITLAs, but in a form that will enable integration with other silicon photonics devices. The Pico Laser and COSA are suited to supporting compact 400G pluggable modules such as OSFP and QSFP-DD.
NeoPhotonics new tunable optical filter array product is designed to complement the broad family of multi-cast switch products currently offered by the firm. The array consists of 16 filters integrated on a single photonic chip. It can be integrated into a larger module such as a multi-cast switch or separately packaged. Implementing tunable optical filter functionality in an array form within the ADD/DROP device enables compact transceiver modules without filters to be used in CDC (colorless, directionless and contentionless) networks to reduce the overall cost of a coherent system.
NeoPhotonics is demonstrating a 100G CFP2-DCO coherent transceiver. As an important addition to its ClearLight digital coherent module platform, it is designed for metro-access and 5G backhaul applications where both spectral efficiency and power efficiency are critical. As with the firm’s other platform products, the module is implemented without need for an EDFA amplifier, resulting in a superior optical signal-to-noise ratio (OSNR) and higher link performance, it is claimed.

“We are pleased to demonstrate our new Class 40, 64Gbaud, silicon photonics COSA and our new silicon photonics-based Pico Tunable Laser at OFC, showing that we have achieved the high performance for which our discrete components are known, but in this new highly integrated platform,” says chairman & CEO Tim Jenks. “In addition, we are pleased to enhance our multi-cast switch product line with the addition of tunable filter arrays, and to launch a CFP2-DCO module to our existing DCO module product family.”

NeoPhotonics is exhibiting its suite of coherent components for 600G to 1 Terabit, along with its broad family of products for high-speed applications, in booth 2923 at OFC.
