The Top-Coupling Waveguide Array to Fiber Transposer (TC-WAFT)
The Top-Coupling Waveguide Array to Fiber Transposer (TC-WAFT)
The Top-Coupling Waveguide Array to Fiber Transposer (TC-WAFT) is an essential solution for integrating Photonics Integrated Circuits (PIC) with fiber optics, designed for low-footprint and low-profile optical injection into grating couplers. It is ideal for PIC packaging and wafer-level testing. TEEM's ioNext platform offers a variety of TC-WAFT products, both bare and pigtailed, customizable in terms of port number, output pitch, and output mode size.
- Number of ports: Options available for <32, 32-96, and 96-256.
- Max Insertion Loss: 0.7 dB for <32 ports, 0.9 dB for 32-96 ports, and 1.1 dB for 96-256 ports.
- Insertion Loss Uniformity: Less than 0.2 dB for <32 ports and less than 0.3 dB for 32-256 ports.
- Max Polarization Dependent Loss: 0.1 dB for <32 ports and 0.2 dB for 32-256 ports.
- Max Adjacent Crosstalk: -30 dB for <96 ports and -25 dB for 96-256 ports.

- Minimum Output Pitch: 20 µm.
- Outputs Positioning Relative Accuracy: +/- 0.05 µm for <32 ports and +/- 0.1 µm for 32-256 ports.
- Polarization Extinction Ratio: Greater than 25 dB.
- Operating Wavelength: 1200 - 1700 nm.
- Fibre Connection: Available with SM or PM fibres and connectors such as FC, SC, ST, LC, or MPO.
- Custom Chip Designs: Options for variable output pitches and additional optical functions like taps and splitters.
- Custom Chip Dimensions and Shaping.
- PIC packaging with grating couplers.
- Wafer-level testing with edge couplers.
Catalog excerpts
DESCRIPTION The Top-Coupling Waveguide Array to Fiber Transposer (TC-WAFT) is the must-have PIC-to-fiber solution for a low-footprint, low-profile optical injection into grating couplers. It is perfectly suitable for PIC packaging and wafer-level testing. Thanks to its ioNext platform (Photonics Integrated Circuits on glass), TEEM offers a whole range of bare and pigtailed TC-WAFT products, with user-defined port number, output pitch and output mode size.
