We propose a highly sensitive optical sensor which is built from silicon nanowires. The silicon nanowires are arranged to form a ring resonator. The silicon nanowires cladding and voids are filled with the analyte. The sensor has a small footprint of 16 μm × 16.5 μm. The insertion loss of the sensor is only 0.4 dB, while it is characterized by its high sensitivity of 430 nm/ RIU. As a biosensor, our device showed a 100 nm/RIU sensitivity when a thin biolayer of 10 nm thickness is attached to the silicon nanowire structures.

“…Optical routers and multiplexers show high potential for transferring data between optical nodes with speeds matching the high-speed data transmission through optical fibers. Optical routers and splitters [3] based on integrated optical devices are usually based on photonic components such as multimode interferometers (MMIs) [4][5][6], Mach Zender interferometers [7,8], directional couplers [9,10], and ring resonators [11,12].…”

The demand on fast and high-bandwidth data transmission is in continuous increase. These demands are highly dependent on optical signal manipulation, including switching, modulation, and routing. We demonstrate a two-port silicon optical router based on the multimode interferometer (MMI) configuration. The same MMI structure was used for both inward and backward waveguiding to reduce the total length of the device. A phase shifter consisting of two ring-like waveguides made of silicon p-n junctions was used to introduce the phase shift needed for optical routing upon voltage application. Two designs for the MMI optical router were studied: Firstly, a conventional MMI with a crosstalk ratio of 15.1 dB was investigated. Finally, an angled MMI reaching a crosstalk ratio of 18.2 dB at a wavelength of 1.55 μm was investigated.

“…Thus, the SOH platform was introduced to benefit from the strong wave guiding properties of Si and the EO effects of the integrated organic materials or electro-optic polymers EOPs (Leuthold et al 2013). SOH modulators based on different devices (Mohamed et al 2018;Pan et al 2018;Wolf et al 2018) were demonstrated.…”

Optical modulation is an essential process in the telecommunication technology. A sub-femtojoule optical modulation based on low loss hybrid plasmonic waveguide which integrates silicon, metal, and electro-optic material is demonstrated. Modulation is achieved through applying modulating voltage across the electro-optic layers. Firstly, a directional coupler modulator is designed and simulated, it showed a modulation depth of 26 dB, and energy consumption of 0.8 fJ/bit. Secondly, a Mach Zender interferometer circuit based modulator is designed and analyzed, with a modulation depth of 32 dB, and energy consumption of 0.8 fJ/bit.
