Ajbrui delivers dynamically configurable Integrated Components for optical communications vendors and optical interconnects. Ajbrui pursues these technological challenges utilizing its innovative Moving Waveguide technology.
Receiver Protection Module

Ajbrui’s Receiver Protection Module (RPM ) resolves the effects of wide variations in network loading experienced in WDM receivers. Additionally, it can resolve spikes in optical power, which can potentially damage receivers.

Ajbrui’s unique technology for wafer level sealing achieves high quality and reliability at a relatively low cost.


  • Size – Ajbrui silicon technology enables the miniaturization of the RPM to 1x2mm, to allow integration with exisiting receiver packages.
  • Fast Reponse Time – Ajbrui protection device is faster than 300ms, which is much faster than the response time needed for receiver protection.
  • Integrated monitoring PD – Ajbrui offers integrated monitoring PDs, which are vital for receiver protection.
  • Accurate passive alignment ability – Ajbrui multimode silicon waveguides enable a breakthrough of existing methodology with passive alignment of fiber-to-device.
