An integrated optical transceiver, comprising a 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; and a 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; and an electrically insulating material separating the photodiode substrate from the first heat sink and being air or dielectric material with a relative dielectric constant &#x3b5;&#x3c;10, wherein the electrically insulating material provides a gap having an effective electrical distance of at least 80 &#x3bc;m between the photodiode substrate and the first heat sink.

Integrated optical transceiver

An electrical connection interface is provided. The electrical connection interface includes a first ground plane layer, a second ground plane layer, a first substrate and a second substrate. The second ground plane layer is positioned to overlap the first ground plane layer. The first substrate includes a first substrate conductive lead with a first interface region connected to and electrically insulated from the first ground plane layer. The second substrate includes a second substrate conductive lead with a second interface region connected to the first substrate conductive lead and the second ground plane layer. The second substrate conductive lead is electrically insulated from the second ground plane layer.
