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.
