Use of photons for in-situ measurements of various objects provides a number of benefits, such as precise real-time measurement with no effect on the measured objects. Our research aims to develop an in-situ measurement technology that uses the benefits of photons and is ideal for applications in production lines. We succeeded in developing a tunable laser beam source to obtain the spectral line width of 5 MHz and a continuous wavelength sweep bandwidth of 200 nm, thus achieving our initial target. We believe that these characteristics are sufficient for use in absorption spectroscopy measurement of gases. For a 2.5-2.7 μm-band quantum infrared photo detector, we achieved the initial target of D* = 1 to 3 × 10 11 cmHz 1/2/W (at room temperature). For a 3-10 μm-band quantum infrared photo detector, we performed a study on designing an InAsP/InP multi-quantum well light-absorbing layer.
