The proposed device opens a new window to the design and fabrication of tunable graphene-based photonic crystal circuits to develop electro-optic on-chip processing systems. This tunable ultrafast device supports a maximum sampling rate of up to 222 GS/s, whereas its compact footprint is about $$. For appropriate chemical potential values of GNS, each resonant cavity can drop the optical beam into its corresponding output port. The electro-optic demultiplexer is realized using three GNS-based photonic crystal resonant cavities and can be tuned by applying different biasing of the gate voltage to the GNSs. The first part provides sampling and quantization of the input electrical analog signal based on the applied potential to the graphene nanoshells (GNSs), while the second part converts the quantized levels into two-bit binary code. The proposed structure consists of a tunable three-channel demultiplexer and an optical encoder. In this paper, we propose a novel design of a tunable electro-optic analog-to-digital converter.

Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.

Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.

Use these formats for best results: Smith or J Smith.

For best results, use the separate Authors field to search for author names.

Use quotation marks ' ' around specific phrases where you want the entire phrase only.

Question mark (?) - Example: 'gr?y' retrieves documents containing 'grey' or 'gray'.

Asterisk ( * ) - Example: 'elect*' retrieves documents containing 'electron,' 'electronic,' and 'electricity'.

Improve efficiency in your search by using wildcards.

Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.

Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters.
