The team fabricated 11-mm-long polymer waveguides using direct laser writing on FR4 glass-epoxy substrates. The waveguides had well-controlled core dimensions (9.0 µm × 7.0 µm), suitable for ...

TOKYO-- (BUSINESS WIRE)-- Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has developed a slotted waveguide array antenna made of injection-molded resin which have been ...

High-speed optical circuits and sensors generally require strict control over light polarization to minimize loss and cross-talk in photonic devices such as waveguides. An A*STAR team now predicts ...
