We have demonstrated a bidirectional wavelength division (de)multiplexer (WDM) on the silicon-on-insulator platform using two 4-channel angled multimode interferometers (AMMIs) sharing the same multimode interference waveguide. An excellent match of

We demonstrate a suspended germanium waveguide platform with a propagation loss of 5.3 dB/cm at a wavelength of 7.7 µm, with potential applications in free-space optical communications and absorption sensing. Furthermore, our simulations show low-lo

The mid-infrared (MIR) wavelength region contains unique absorption fingerprints of many molecules and substances. Therefore, the main application area in the MIR can be sensing. Si and Ge are transparent in this range (Si up to 8 μm, and Ge up to 1

Germanium has become a material of high interest for mid-infrared (MIR) integrated photonics due to its complementary metal-oxide-semiconductor (CMOS) compatibility and its wide transparency window covering the 2-15 μm spectral region exceeding the

Experimental demonstrations of silicon-on-insulator waveguide-based free-carrier effect modulators operating at 3.8 μm are presented. PIN diodes are used to inject carriers into the waveguides, and are configured to (a) use free-carrier electroabsor

Recent developments of photonic integrated circuits for the mid-infrared band has opened up a new field of attractive applications for group IV photonics. Grating couplers, formed as diffractive structures on the chip surface, are key components for
