Single Mode CWDM4 Mux/Demux Coupler, FlexBeamGuidE™-WD
Featuring CWDM capabilities in between single mode fiber and PIC
By utilizing Mach-Zehnder Interferometer (MZI) made of Planar Lightwave Circuit (PLC) technology
The PLC is designed for single-mode operation and emits output beam that is easily coupled with Silicon photonics chips and high-speed PD arrays. This makes it well-suited for Co-packaged Optics and high-speed optical transceiver applications. The use of SiO₂ material achieves low polarization-dependent loss and also ensures long-term reliability.
- Single-mode waveguide can be coupled with a PIC at ease
- Small beam divergence gives better coupling efficiency with small dia. PDs for high speed application
- Small foot print of waveguide realizes multiple Mux/Demux functions on a single chip
Applications
-
800G / 1.6T FR4/8 transceivers
-
Beyond 3.2T co-packaged optics (CPO)
