Abstract
Gallium arsenide optical fiber temperature sensor Small probe size 0.5mm temperature measurement accuracy ±0.1℃
Gallium arsenide (GaAs) optical fiber temperature sensor is a kind of non-contact temperature measurement system based on semiconductor optical characteristics, which realizes high precision temperature measurement through the principle that the light absorption or fluorescence characteristics of GaAs materials change with temperature. Its core advantages in all-optical signal transmission (no electromagnetic interference), small probe size (as small as 0.5mm), resistance to extreme environments (high voltage, strong corrosion, strong electromagnetic field, etc.), widely used in semiconductor, electric power, medical and scientific research fields.
Working principle
(1) Absorption side temperature measurement type
Principle: The wavelength of the light absorption side of GaAs
shifts towards the long wave direction (~0.4nm/℃) with the increase
of temperature.
Implementation method:
Broadband light sources (such as leds) transmit optical signals to the GaAs probe through optical fibers.
GaAs chips absorb specific wavelengths of light (absorption side wavelength is temperature-dependent).
The reflected light signal is returned to the demodulator and the temperature is calculated by spectral analysis.
Features: Simple structure, low cost, suitable for industrial applications (such as power equipment monitoring).
(2) Fluorescent lifetime temperature measurement type
Principle: The lifetime of GaAs stimulated emission fluorescence is
inversely proportional to temperature.
Implementation method:
The pulsed laser excites the GaAs probe to produce fluorescence.
The fluorescence decay time (lifetime) is detected, and the temperature is converted by calibration curve.
Features: Higher accuracy (±0.05℃), suitable for medical and scientific research fields.

New energy: hot spot detection of lithium battery pack and photovoltaic inverter.
(3) Medical and biological
Minimally invasive surgery: radiofrequency ablation tip temperature
real-time feedback (probe can be integrated into catheter).
Biological experiments: cell culture, temperature calibration of PCR instrument.
(4) Scientific research and extreme environment
Aerospace: Measurement of combustion chamber temperature of rocket
engines (resistance to high temperature and vibration).
Nuclear industry: Reactor cooling piping monitoring (radiation-resistant design).
(5) Industrial process control
Chemical piping: Temperature monitoring in corrosive media (acid
and alkali resistant package).
Iron and steel metallurgy: continuous casting billet surface temperature measurement (fast response, thermal shock resistance).
Q&A
1. Q: What is a gallium arsenide (GaAs) fiber optic temperature
sensor?
A: It's a high-precision, EMI-immune temperature sensor that uses
GaAs crystal's optical properties to measure temperature through
fiber optics, ideal for harsh environments.
2. Q: How does a GaAs fiber optic temperature sensor work?
A: It detects temperature by measuring either the wavelength shift
of GaAs's absorption edge or the decay time of its fluorescence,
transmitted via optical fiber.
