When a regularly structured element or diffraction grating is included in the active zone of a laser diode, quantum cascade laser, or optical fibre laser, the device is referred to as a distributed-feedback laser (DFB). A one-dimensional interference grating is created by the structure (Bragg scattering), and the grating gives the laser optical feedback.
Periodic changes in the refractive index of this longitudinal diffraction grating result in reflection back into the cavity. The refractive index's periodic change might occur in either the real or imaginary parts (gain or absorption). The first order, where the periodicity is one-half wave, is where the strongest grating operates, and this is where light is reflected backwards.
The Global Distributed Feedback (DFB) Laser Diode Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The DFB laser driver was developed, and experiments were shown. Self-designed circuits are used to construct this laser driver. It has the capacity to modulate crucial signals using the TDLAS approach and regulate laser temperature, driving current, and other parameters.
The modulated DFB laser may be used as the system's radiation source for detecting gases. A linear power supply circuit has been created to meet the needs of the system in order to deliver steady and low-noise power supply.
To assess and improve the functionality of the DFB driving circuits and control algorithm, spectroscopy measurements have been made. Only to orient the audience and establish units is the applied gas-sensing theory briefly explained.
Through 15 hours of monitoring on the laser's emitting wavelength, the temperature fluctuation of the laser can be kept to a maximum of 0.02 to 0.02°C, and good operation stability was noticed.
It was determined through testing that the response time of temperature modulation meets the tuning needs of gas detection systems. Within the range of 40 to 80 mA, laser current can be injected. To provide a reliable and low-noise power source for the system, a linear power supply circuit has also been created.
The suggested low-cost circuits can take the place of expensive commercial equipment in driving the laser to suit the needs of studies for methane detection. By adjusting the circuit's settings and the light source's lasers, it may also be used to detect different gases.
