“…In Liu et al, 43 a low‐loss and low‐crosstalk on‐chip triplexer on silicon was proposed and demonstrated with three cascaded‐MWG‐based filters (see Figure 11A). The structure design is similar to the CWDM filter based on cascaded MWGs.…”

“…Currently, silicon photonic filters have been used widely as a key role in not only the wavelength‐division‐multiplexing (WDM) systems but also spectroscopy sensing. Here, we mainly focus on silicon‐based on‐chip WDM filters with different structures, such Mach‐Zehnder interferometers (MZIs), 12‐19 micro‐ring resonators (MRRs), 20‐34 waveguide Bragg gratings, 35‐46 arrayed‐waveguide gratings (AWGs), 47‐64 and echelle diffraction gratings (EDGs) 62,65‐67 . Figure 1 gives a summary of the reported on‐chip photonic filters based on silicon‐on‐insulator (SOI) nanophotonic waveguides.…”

Photonic filters are playing a very important role in many applications, including optical interconnects as well as optical sensing. As silicon photonics has provided a very attractive platform to realize the high integrated intensity and low cost, various silicon‐based on‐chip photonic filters have been proposed and demonstrated in the past decade. In this paper, we give a review of recent progresses of silicon photonic filters based on different structures, including Mach‐Zehnder interferometers, microring resonators, waveguide Bragg grating, and arrayed‐waveguide gratings.

“…Most previous researches were concentrated on the near infrared (NIR) bands (1300 -1700 nm), especially at 1310 nm, 1490 nm, and 1550 nm, which are widely used in the fiber-to-the-X (FTTX) systems. The schemes mainly contain grating couplers [2,3], directional couplers (DCs) [4,5], Photonic crystals [6,7], multimode interference (MMI) couplers [8,9], Mach-Zehnder interferometers (MZIs) [10], inversely designed metamaterials [11], and so on. In response to the rapidly growing demand of networks, it is extremely necessary to exploit a new telecommunication window.…”

A high contrast and compact wavelength diplexer is presented for conventional 1550 nm and emerging 2000 nm based on a subwavelength-grating (SWG) coupler. The SWG silicon waveguide thoroughly blocks the light propagation around 1550 nm but fully supports 2000 nm (extinction ratio: 43.11 dB). This grating type anisotropic metamaterial not only efficiently reduces the coupling length but also expands the operational bandwidth. Simulated by 3D finite-difference time-domain method, the proposed diplexer possesses remarkably low insertion loss and high contrast of 25.24 (31.7) dB at 1550 (2000) nm. The operational bandwidth of 200 (108) nm is achieved with contrast over 15 dB and insertion loss below 0.22 dB. The footprint of diplexer is only 5.27 μm × 11.85 μm. Moreover, such design has the scalability by simply tuning the geometrical parameters of SWG.

Nonreciprocal photonic devices are essential components of classical optical information processing. It is interesting and important to investigate their feasibility in the quantum world. In this work, a single‐photon non‐reciprocal dynamical transmission experiment has been performed with an on‐chip silicon nitride (SiN)‐based magneto‐optical (MO) isolator. The measured isolation ratio for single photons achieved is 12.33 dB, consistent with the result of the classical test, which proves the functionality of our on‐chip isolator. The quantum coherence of the passing single photons is further verified using high‐visibility quantum interference. This work will promote on‐chip nonreciprocal photonic devices within the integrated quantum circuits and help introduce novel phenomena in quantum information processes.
