Proposal for 4-to-2 optical encoder based on photonic crystals
TLDR
In this study, an all optical 4-to-2 encoder have been proposed which has four input and three output ports and can generate a 2-bit binary code considering which input port is active.Abstract:
In this study, an all optical 4-to-2 encoder have been proposed which has four input and three output ports. The proposed structure can generate a 2-bit binary code considering which input port is active. For realising the proposed structure first the authors proposed and designed a BUFFER and an OR gate. Then combined these basic gates to realise the proposed encoder. The maximum switching delay and footprint for the proposed structure are about 200 fs and 880 μm2, respectively.read more
