Telecoms ♦ news digest parallelisation into the optical interconnects.
What’s more, the project partners will develop new assembly processes based on 3D-integration of electronic and optical components to effectively blend silicon, glass and III-V photonic elements with CMOS electronic drivers.
In this project, imec’s associated lab at Ghent University will develop the dedicated high- speed low-power VCSEL driver array and the transimpedance amplifier array. In these IC designs, imec will focus on the close integration and matching of the drivers with the corresponding VCSEL/photodiode arrays. The team will co- optimise the electronic circuits, parasitic elements, interconnects and optical-electronic-optical component parameters to take advantage of the various new technologies developed by the MIRAGE consortium.
Imec will also develop an innovative methodology to simplify bonding the MIRAGE active add-ons to the silicon platform. For VCSEL and photodiode bonding, in particular, tight alignment tolerances usually require costly equipment whereas the large distance between VCSELs and waveguides necessitates the use of microlenses to account for the beam divergence.
MIRAGE will confront these costs with a self- alignment assembly process based on microbumps.
Emcore unveils 1550nm fibre optic transmitters and receivers
The III-V based devices support multiple format frequency transport in a single platform for C, X, Ku, and Ka-band applications
Emcore is launching Optiva Satcom Band Microwave fibre optic transmitters and receivers for satellite communications, RF antenna remoting and other high-dynamic range microwave applications.
These new products supplement the existing Emcore Optiva Ultra-Wideband RF Fibre Optic Transport System by adding band-specific C, X, Ku, or Ka transmitter and receiver modules compatible
with Emcore’s modular or flange-mount Optiva Platform configurations.
Optiva Microwave Fibre Optic Transport System
The Optiva Satcom Band RF Fibre Optic Transport System expands on the existing Optiva Platform that already supports 50 MHz to 18, 22 or 40 GHz broadband microwave transport, reference oscillators, IRIG, IF, L & S-band, plus audio, video, data and Ethernet. Emcore says this makes it one of the most universal platforms in the industry.
“The Optiva Satcom Band RF Fibre Optic Transport System represents a significant breakthrough in microwave transmission technology from Emcore,” says Frank Weiss, Vice President of Emcore’s Advanced Systems Division. “By leveraging our existing ultra-wideband 50 MHz – 40 GHz Optiva products as building blocks, Emcore is able to provide high-performance externally modulated RF- banded technology at directly modulated technology price points. Additionally, these new products support multiple format frequency transport in a single flexible platform for C, X, Ku, and Ka-band applications.”
Utilizing Emcore’s high-performance ultra-low Relative Intensity Noise (RIN) source laser technology and high optical input power capable photodiodes, the Optiva Satcom Band RF Fibre Optic Transport System provides a high-dynamic range of over 110 dB-Hz2/3. The system features microprocessor-based transmitter and receiver control for laser and modulator bias and variable RF link gain which provides consistent high- performance and constant gain operation.
The standard Optiva transmitter provides a high power optical output and operates at a nominal wavelength of 1550 nm. Wavelength selected
