      abstract     = {A concept and design of a 50-Gbps 4-channel dense
                      wavelength division multiplexing (DWDM) optical transceiver
                      is being developed. It is designed in a 45-nm monolithic
                      silicon-photonics CMOS technology. The design targets to
                      meet the rising data throughput requirements of
                      high-resolution detectors in high-energy physics and photon
                      science. We discuss the key components of the transceiver,
                      emphasizing high-speed ring modulators, ring resonators and
                      their electronic circuitries, highlighting the advantage of
                      the monolithic integration. The transmitter concept is based
                      on multi-wavelength light coupled into a single waveguide to
                      be modulated by cascaded ring modulators at their resonant
                      wavelengths within free spectral range of 9.3 nm. The
                      dedicated electronic circuitry to modulate ring modulators
                      contains custom-designed 10-to-1 multiplexer followed by a
                      dedicated driver with asymmetrical differential voltage of
                      1.5 V. The multiplexer and driver consume only 0.7 pJ/b at
                      12.5 Gbps. An array of four 2nd order ring resonators are
                      cascaded to demultiplex the transmitted spectrum at the
                      receiver side. The spacing between the channels is designed
                      to be 400 GHz (2.1 nm) to ensure the device peformance. We
                      examine the temperature dependencies of ring modulators and
                      resonators to determine the tuning range available by
                      biasing the heating element. Furthermore, the correlation
                      between crosstalk among the channels and channel spacing is
                      addressed. Through comprehensive electrical-optical
                      co-design simulations, we present the feasibility and
                      performance potential of our proposed optical transceiver
                      paving the way to realize efficient and compact detector
                      systems.},
