Hybrid photonic integrated circuit expert, NeoPhotonics, at the OFC event, is demonstrating its Silicon Photonics based 64 Gbaud Coherent Optical Sub-Assembly (COSA). Additionally, the company is demonstrating its Silicon Photonics based ultra-narrow line width Pico Tunable Laser and a single chip array of tunable optical filters, both of which can be integrated with other photonic integrated circuits or separately packaged. Finally, the company is also demonstrating its new CFP2-DCO pluggable coherent module.
Highlights of NeoPhotonics display at OFC 2019:
- Class 40, 64 Gbaud, Silicon Photonics based COSA contains a coherent I/Q modulator and coherent receiver fabricated using Silicon Photonics and based on NeoPhotonics designs. This Photonic Integrated Circuit (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. The COSA is approximately half of the size of the current discrete component solution.
- The Silicon Photonics based Pico Tunable Laser utilizes the same unique, high performance external cavity architecture as its industry leading 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 well suited to support compact 400G pluggable modules such as OSFP and QSFP-DD.
- New tunable optical filter array product is designed to complement the broad family of multi-cast switch products offered today by NeoPhotonics. The tunable optical filter array consists of 16 filters integrated on a single photonic chip. The array 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 networks to reduce the overall cost of a coherent system.
- Finally, NeoPhotonics is demonstrating a 100G CFP2-DCO coherent transceiver. It is an important addition to NeoPhotonics' ClearLight digital coherent module platform, powered by our industry leading high performance optical components. It is designed for metro-access and 5G backhaul applications where both spectral efficiency and power efficiency are critical. As with our other platform products, this module is implemented without need for an EDFA amplifier, resulting in a superior OSNR and higher link performance.
NeoPhotonics is exhibiting its suite of coherent components for 600G to a Terabit transmission at the event in San Diego in Booth 2923 from March 5th to 7th, along with its broad family of products for high speed applications.
