Abstract

This disclosure is directed to optical-to-electrical receiver and transceiver integrated circuits that can be used to send and receive multiple optical signal data streams using at least one optical bus. In one aspect, a fan-in integrated circuit of a node includes an arbiter/multiplexer, and at least one receiver. Each receiver is electronically connected to the arbiter/multiplexer. Each receiver receives at least one optical signal over an optical broadcast bus and converts the optical signals into a data stream encoded in electronic signals. The arbiter/multiplexer selects one receiver at a time to send an electronic signal to the arbiter/multiplexer and outputs the electronic signal to the node for processing.

First claim

The invention claimed is:

1. A fan-in integrated circuit of a node comprising:
an arbiter/multiplexer;
a plurality of receivers, each receiver electronically connected to the arbiter/multiplexer, wherein each receiver is configured to receive optical signals over a corresponding optical broadcast bus and convert the optical signals into a data stream encoded in electronic signals, and each receiver comprises an array of photodetectors, where each photodetector receives and conve…
