    • An optoelectronic integrated circuit (OEIC) having an optical core coupled to first and second interface circuits. The first interface circuit is adapted to convert an electrical input signal into an optical signal; the optical core is adapted to process the optical signal in the optical domain; and the second interface circuit is adapted to convert the processed optical signal into an electrical output signal. In one embodiment, an OEIC of the invention is fabricated using a single wafer, has only electrical inputs/outputs, does not have any external optical interfaces, and is not adapted to receive any external optical signals. Advantageously, due to the signal processing being in the optical domain, a circuit of the invention carries out its functionality, with little or no performance degradation, over a relatively wide frequency range. In addition, this circuit has a relatively small size and can be relatively inexpensive.
    • 一种具有耦合到第一和第二接口电路的光纤的光电集成电路(OEIC)。 第一接口电路适于将电输入信号转换为光信号; 光芯适于处理光域中的光信号; 并且第二接口电路适于将经处理的光信号转换为电输出信号。 在一个实施例中,使用单个晶片制造本发明的OEIC,仅具有电输入/输出,不具有任何外部光学接口,并且不适于接收任何外部光学信号。 有利地,由于信号处理在光域中,本发明的电路在相对较宽的频率范围内执行其功能很少或没有性能下降。 此外,该电路具有相对小的尺寸并且可以相对便宜。
