Patent ID: 10659166

Abstract:
An integrated optical transceiver, comprisinga laser component, comprising an array of VCSEL diodes formed on a laser diode substrate;a laser driving component, comprising laser diode driving circuitry formed on a laser driving circuitry substrate;a photodiode component, comprising an array of photodiodes formed on a photodiode substrate; anda photodiode driving component, comprising photodiode driving circuitry formed on a photodiode driving circuitry substrate;a first heat sink comprising a connected piece of material to transport excess heat away from the integrated optical transceiver and connected to both the laser and photodiode driving components; andan electrically insulating material separating the photodiode substrate from the first heat sink and being air or dielectric material with a relative dielectric constant ε<10, wherein the electrically insulating material provides a gap having an effective electrical distance of at least 80 μm between the photodiode substrate and the first heat sink.
