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 supporting all-optical signal processing and photonic integration in
fiber-optical communication.
