Hamamatsu Photonics: Terahertz wave / variable semiconductor laser development:
-The world’s first analysis of the generation principle of “terahertz waves”-
Hamamatsu Photonics:
We analyzed the generation principle of “terahertz waves with intermediate characteristics between radio waves and light”.
“Terahertz wave”:
The frequency of the terahertz wave,
Can occur by switching each time
Developed the world’s first semiconductor laser.
Output is 5 times or more:
New technology is used to process high resistance silicon lenses.
Output of terahertz waves. Succeeded in increasing more than 5 times the conventional value.

Realized the world’s first QCL module
-Frequency variable range 0.42 to 2THz-
Hamamatsu Photonics:
We analyzed the principle of terahertz wave generation.
Quantum cascade laser
Quantum Cascade Laser
In addition to increasing the output of QCL
A highly efficient external resonator (* 3) was manufactured using our unique optical design technology.
Realization of new QCL module:
In the range of 0.42 to 2 terahertz,
We have realized a new QCL module that generates terahertz waves of any frequency.
Results of this research:
In one module
By switching the frequency, a narrow band terahertz wave can be generated.
Areas of use:
Contains components that absorb terahertz waves,
Drug,
Food,
Semiconductor materials, etc.
You can improve the accuracy of quality evaluation, non-destructive inspection, identification of polymer materials, etc.
Realization of ultra-high-speed wireless communication:
Using terahertz waves,
It can be applied to innovative key devices for the realization of ultra-high-speed wireless communication in the future.
