Two-mode multiplexer based on the multilayer Si-SiN platform for 2μm waveband

We experimentally demonstrated a two-mode multiplexer in the multi-layer Si-SiN platform for 2µm waveband. The insertion loss of the mode multiplexer link is less than 2.2 dB across the wavelength 1945 nm-1985 nm

Silicon nitride waveguiding for prospective technologies at the 2 μm waveband

Of late, the 2 µm waveband has gained significant recognition in terms of enabling potential key technological applications. In response, we propose the Si3N4-SOI platform at the 2 µm waveband. The insertion loss of the Si-Si3N4 adiabatic interlayer coupler is characterized to be 0.05 dB/transition. Si3N4 waveguide propagation losses as low as 1.59 dB/cm have been achieved. <br/

Silicon optical modulators for data transmission in different wavelength bands

High-speed and low-power silicon optical modulators are key in realising low cost photonic circuits for data transmission purposes. Depending on the application, different wavelength bands are preferred and therefore designs of optical modulator, which operate in these bands, are required. Here we present our recent work on silicon optical modulators at 1310, 1550, 2000 and 3800 nm wavelengths
