In this paper, we exploit high refractive index silicon oxycarbide (SiOC) thin films. SiOC thin films deposited by RF sputtering were used to simulate, design, and fabricate photonic devices such as channel waveguides and Mach-Zehnder interferometers (MZIs). The fabricated micro-photonic structures were tested on a controlled optical setup to estimate the thermo optic coefficient (TOC) at the standard telecommunication wavelength 1550 nm. With refractive index of 2.2 the thermo-optic coefficient of silicon oxycarbide using Mach-Zehnder interferometer was measured as 2.6 x 10-4 RIU/℃ that is highest among the dielectric platforms. Our research presents silicon oxycarbide as potential platform for the realization of highly efficient reconfigurable integrated photonic systems.

Since it was announced by the President of the Republic of Indonesia on March 2, 2020, regarding the discovery of Covid 19 or corona cases in Indonesia, cases of corona sufferers have increased and spread to all corners of Indonesia. One of the characteristics of the Corona Virus is that it survives on the surface of objects held by the exposed person. Therefore, avoiding contact with objects that are shared is one way to prevent the spread of this virus. The gate and front door of the house are the most vulnerable objects as a place for the Corona virus to spread. This is because the gate and front door of the house are located outside the house and are in direct contact with many people passing by. Microcontroller technology combined with a sound sensor via Bluetooth connection can function as an automatic door opening and closing lock that can prevent users from touching when they have to open the door. The microcontroller technology combined with a sound sensor via a Bluetooth connection can function as an automatic opening and closing key that prevents users from touching when they have to open the door.
