ZrO2 thin-film-based sapphire fiber temperature sensor

ZrO2 thin-film-based sapphire fiber temperature sensor.

A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected as the thin film material to fabricate the temperature sensor because it has relatively close thermal expansion to that of sapphire, but more importantly it does not react appre...

Fiber-Tip Fabry-Perot Interferometric Sensor based on a Thin Silver Film

Fiber-optic sensors have many advantages, including small size, light weight, immunity to electromagnetic interference, and the capability of remote sensing. Fiber-tip sensors are fabricated on a fiber tip and are the smallest type of fiber-optic sensor. The fiber-tip sensors have attracted a great deal of attention in past years for pressure, temperature, and acoustic sensing. In this thesis, ...

Thin film PIN photodiodes for optoelectronic silicon on sapphire CMOS

In this paper, we consider both the utility of SOS substrates as a vehicle for optoelectronic packaging and the high speed silicon photodiodes available on a commercial SOS process. We show optical responses for six configurations of PIN photodiodes designed in this process. Our results indicate that photodiodes native to this process will operate at better than gigabit rates and produce signal...

Nonlinearity Mechanism and Correction of Sapphire Fiber Temperature Sensor on Blackbody Cavity

Based on the principle of blackbody radiation, sapphire optic fiber temperature sensor has been more widely used in recent years, and its temperature range is between 800 ~ 2000 oC, and the response time is in 10-2 magnitude, and transient temperature measurement can be high precision in harsh environments. Nonlinear constraints on sapphire fiber temperature sensor affect the accuracy and stabi...
