Abstract
The exponential growth of internet traffic continues unabated with proliferation of bandwidth-hogging applications and mobile devices. The speed at which the data traffic has been increasing has outstripped the pace of Moore’s law and is beginning to challenge the optical transport capacity, which until quite recently was considered abundant and cheap. Lately, the strategy to increase the optical transport capacity has centered on more efficient use of easily available optical spectrum by using complex multi-level modulation formats, as the available optical wavelengths become fully lit. At the same time, the fiber optical communication is becoming more computationally intensive as it is beginning to rely on coherent reception and computational penalty mitigation. This reliance on high-speed electronic signal processing poses two significant challenges, which are increased energy consumption and network latency. Signal processing in the optical domain, especially using compact photonic integrated devices, is an alternative that can offer substantial reduction in energy consumption with increased processing speed. In this talk, I will present my recent activities at Bell Labs supporting all-optical signal processing and photonic integration in fiber-optical communication.
