LD-PD makes chips closer to applications

We know how to change this.

Semiconductor lasers operating globally

The semiconductor laser developed by LD-PD is currently operating for 7X24 hours in different application areas of its partners. Advanced semiconductor technology combined with our unique optical design ensures that our 10k+laser can run in real time "without any errors"

Technology


We seamlessly connect semiconductor chips to various application fields, including emerging industries such as quantum communication, fiber optic sensing, high-speed communication, and biomedicine.

ACCURATE WAVELENGTH SCREENING

LD-PD can perform wavelength screening on COC chips, providing photon chips with a tolerance better than ± 1nm. LD-PD has a near-infrared high-speed acquisition wavelength meter, and a mid infrared FTIR Fourier spectrometer for strict screening of all wavelengths

AUTOMATIC POWER MONITORING

The fully automatic L-I-V curve detection system independently developed by LD-PD greatly improves the efficiency of semiconductor laser testing. It automatically measures the relationship between laser power and driving voltage with current changes, and draws relevant curves in real time

PRECISION SPECTRAL ANALYSIS

Anritsu MS9740B Spectral Analyzer covers 600-1750nm, 0.07nm resolution, dynamic range 70dB, AQ6375E mid infrared spectrometer 1000-2500nm resolution, 0.05nm dynamic range 50dB

CHARACTERIZATION OF BEAM QUALITY

Beam quality is an important aspect of laser beam characterization. LD-PD analyzes the 2D/3D profile of the laser beam, evaluates M2, and analyzes the beam quality of the laser
