In addition to being able to design and manufacture their own glass-photonic circuits from the ioNext platform developed by Teem Photonics (see the presentation made on the pages devoted to the two technologies ioNext-NIR and ionNext-VIS), CMP users are also offered access to the WAFT (for Wave-guide Array to Fiber Transposers), glass interposers which are inserted between a silicon-photonics chip and an optical fiber array to ensure between these two elements a single-mode, wideband adiabatic transition, with a coupling loss of less than 0.5dB and a significant reduction in the input/output channels footprint.
Two types of WAFT (corresponding to the two silicon photonics coupling configurations) are available:
edge-coupling WAFT, designed to butt-couple with silicon-photonic chip facets, featuring a wideband transmission and handling both polarization states;
top-coupling WAFT, which provide full multichannel compatibility with grating couplers usually found on silicon-photonics chip.
Teem Photonics also makes its fiber pigtailing know-how available to CMP users by assembling both its WAFT and customized photonic chips with fiber arrays, thus offering lab-ready components.
