An Overview of Integrated Photonic Devices for Energy Efficient Transmitters used in Optical Interconnects
Published in International Conference on Transparent Optical Networks (ICTON), 2020
In this paper, various components required for the realization of transmitters to be used for short-range optical interconnects are presented and their performance is studied using either numerical simulation or lab measurements. Optical modulators, thermos-optic phase shifters, and frequency combs are investigated in this article.

Thermo Optical Phase Shifter With Low Thermal Crosstalk for SOI Strip Waveguide
Published in IEEE Photonics Journal, 2021
To obtain better efficiency, in previous studies, doped silicon heaters are mainly used in the slab of a rib waveguide or implemented inside an expanded strip waveguide. These structures, however, result in a higher bending and propagation loss which is not affordable for some applications where low optical loss is required. We studied an optimized design for a strip waveguide that provides relatively low power consumption (13mW), fast response, and low thermal crosstalk.

End-fire optical phased array with a wide beam-steering for near-visible infrared applications
Published in Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
Recent emerging applications in LiDAR, free-space data link, projection, and imaging increase the demand for high performance optical phased array (OPA). The radiating elements considered for most applications are mainly diffractive elements such as gratings or photonic crystal waveguides. It has been shown recently that edge-emitting waveguide arrays, also known as end-fire, facilitate subwavelength spacing in IR range, which results in a large beam steering.

Efficiency comparison for frequency comb formations in a silicon nitride microring within anomalous dispersion regime
Published in Optics Continuum, 2022
The energy efficiency of silicon nitride (SiN) microresonator-based frequency combs is investigated using numerical simulations. The formation of stable frequency comb solutions is numerically studied for a resonator with properly engineered dispersion.
