Special Issue Information

Dear Colleagues,

Advanced photonics have been explosively expanded to provide novel photonic materials with varied applicability and increase the performance of optoelectronic devices/systems by integrating with them. Already, optoelectronics with photonics have been widely used in diverse fields ranging from light sources, solar energy harvesting, and photodetectors based on anti-/high-reflective structures, photonic crystals, and so forth.

In recent years, advanced photonics have been found to be able to open new pathways to novel applications, including energy-saving technologies (e.g., radiative cooling and solar steam generation), security (e.g., optical physically unclonable function), and biomedical applications (e.g., retinal prostheses). However, novel optoelectronic devices/systems with new photonic materials have barely been reported. In addition to efforts for device-level studies, challenges still remain in terms of enhancing the functionalities of photonic materials for mechanical/chemical/optical features and productibility (i.e., large-scalability and production cost). We invite exceptional scientists and researchers to submit their remarkable results on “Advanced Photonics and Optoelectronic Devices/Systems”.

This Special issue focuses on developments in photonic material itself and integration with optoelectronics. Additionally, comprehensive review articles are invited to summarize achievements of each field and provide a deeper understanding to the scientific communities.

We propose and numerically demonstrate an 800 Gbps silicon photonic transmitter with sub-decibel surface-normal optical interfaces. The silicon photonic transmitter is composed of eight silicon Mach–Zehnder optical modulators and an interleaved AMMI WDM device. This WDM device comprises two 1 × 4 angled MMI and a Mach–Zehnder interferometer (MZI) optical interleaver with an apodized bidirectional grating which has about −0.5 dB coupling loss. Both the Mach–Zehnder electro-optical modulators and MZI optical interleaver regard the bidirectional grating coupler as vertical optical coupler and 3-dB power splitter/combiner. By importing the S-parameter matrices of all the components which have been carefully designed in simulation software, the circuit-level model of the optical transmitter can be built up. On this basis, the static and dynamic performance characterization were carried out numerically. For NRZ modulation, the optical transmitter exhibits the overall optical loss of 4.86–6.72 dB for eight wavelength channels. For PAM4 modulation, the optical loss is about 0.5 dB larger than that of NRZ modulation, which varies between 5.38–7.27 dB. From the eye diagram test results, the WDM silicon photonic transmitter can achieve single channel data transmission at 100 Gb/s NRZ data or 50 GBaud/s PAM4 symbol rate with acceptable bit error rate.
