“…Such approaches can make a trade-off between the CT and power consumption. We also designed a Si MRR-based wavelength-selective 4×4 optical crossbar switch that is similar to those demonstrated by Kazmierczak et al and Zhou et al [67,68], for the purpose of the OSU realization. Now the chip is under manufacturing.…”

“…The MRR-based devices demonstrated in refs. [66][67][68] adopt the passive wavelength-selective operating principle. Among them, our device exhibits much lower CT but at the sacrifice of more power consumption.…”

“…It is due to that the devices demonstrated in refs. [67,68] are true passive without power consumption. However, in practice, the fabrication errors lead the MRR's resonant wavelengths shift and results in the extremely large CT of these devices (as seen in Table 1), which will deteriorate the quality of signal transmission, even cause the bit error.…”

As the transistor's feature scales down and the integration density of the monolithic circuit increases continuously, the traditional metal interconnects face significant performance limitation to meet the stringent demands of high-speed, low-power and low-latency data transmission for on-and off-chip communications. Optical technology is poised to resolve these problems. Due to the complementary metal-oxide-semiconductor (CMOS) compatible process, silicon photonics is the leading candidate technology. Silicon photonic devices and networks have been improved dramatically in recent years, with a notable increase in bandwidth from the megahertz to the multi-gigahertz regime in just over half a decade. This paper reviews the recent developments in silicon photonics for optical interconnects and summarizes the work of our laboratory in this research field. interconnects, optical technology, complementary metal-oxide-semiconductor (CMOS), silicon photonics Citation:Hu T, Qiu C, Yu P, et al.

Abstract-We design and fabricate a four-port wavelengthselective optical router on silicon-on-insulator wafer for photonic networks-on-chip. The router consists of four basic operation blocks. Each is constructed by one microring resonator (MRR) based add-drop filter rather than the traditional two microrings based 2 × 2 optical crossbar. It can provide multiwavelength routing for each path to increase the aggregate data transmission bandwidth. The possible 12 I/O routing paths are experimentally observed in the transmission spectra and each of them has the ability to route four group wavelengths simultaneously in the measured spectral range. The device has a small footprint (∼78 × 100 µm 2 ) and low power consumption (6.58 mW).

Due to the slowdown of Moore's law, the integrated photonic devices have provided a route to promote the development of large‐scale optical communications with high performance. As one of the essential components of optical routers, an optical switch can fast transmit or block the optical signal. However, most of the integrated optical switches reported to date rely on thermo‐, magneto‐, or electro‐optical effects, which limit applications due to slow response times, large footprint, and complexity fabrication. Here, an integrated nonlinear optical switch designed by the inverse‐design method and fabricated on the SiN platform is introduced. The integrated optical switch is demonstrated with significant intensity‐dependent transmission at 1.5 µm waveband. The polarization‐depended capability is explored by using fundamental polarized lights (transverse electric and transverse magnetic, respectively), which exhibits opposite transmission change trends during the whole power range and opens potential applications such as photonic quantum information processing. In order to address the saturation of Kerr‐nonlinearity in SiN materials at high power, a MoS2/SiN hybrid integrated optical switch is fabricated by uniformly cladding few‐layer MoS2 on the surface of inverse‐designed region. That is demonstrated to enhance the nonlinear optical response of device efficiently and achieve more excellent switching capability at high power.
