Micro Optical Bench

At a Glance

  • HHI‘s μBench based on the hybrid integration platform PolyBoard enables the integration of micro-optical functions and elements on photonics integrated circuits (PICs).

Technical Background

HHI’s μBench demonstrates the capability and flexibility of hybrid photonic integration. Features as slots, U-grooves or vertical mirrors allows a hybrid integration of passive or active elements.

Typical passive elements to be integrated: SM fibers, GRIN lenses, crystals, λ/2 plates, λ/4 plates, PBS, thin film filters

Typical active elements to be integrated: lasers, photodiodes, modulators

Micro-medical structures such as U-grooves, slots and vertical mirrors allows for the integration of passive or active optical elements.

Features 

Polymer-based photonic integration platform featuring:

  • U-grooves:
    F/C coupling, GRIN Lenses, free space sections for crystals
  • Slots:
    Thin film elements as λ/2 plate, λ/4 plate, polarization beam splitter (PBS), filters 
  • 45° mirrors:
    PD/VCSEL coupling

Applications

  • Telecom / datacom
  • Quantum technology
  • Microwave photonics
  • Sensing and analytics
  • Medical and life science
