Hamamatsu Photonics has successfully developed a quantum cascade laser (QCL) output power by analyzing the generation principle of terahertz waves, using Hamamatsu's own optical design technology, and high{{0}}efficiency diffraction grating external resonators. The world's first QCL module that can generate terahertz waves of any frequency in the range of 0.422THz.
Ki jan modil QCL la sanble
Rezilta rechèch prensipal yo
1. Pouvwa pwodiksyon an se 5 fwa pi wo pase QCL ki pa lineyè terahertz anvan an. Hamamatsu Photonics analize prensip pwopagasyon vag terahertz andedan QCL ki pa lineyè terahertz, epi li te jwenn ke koneksyon an nan sifas tèt li yo ak yon lantiy Silisyòm ki gen gwo -rezistans ka amelyore efikasite jenerasyon vag terahertz, e li te fè sèvi ak kristal li yo. teknoloji kwasans akimile pandan ane yo. Ak teknoloji pwosesis semi-conducteurs optimize estrikti entèn la pou ogmante pwodiksyon pik nan pwen frekans 1THz nan nivo sub-miliwatt, ki se plis pase 5 fwa QCL tradisyonèl ki pa lineyè.
2. The world's first 0.422THz frequency adjustable QCL module. Hamamatsu Photonics has conducted in-depth research on the material of the anti-reflection film on the top surface of the terahertz nonlinear QCL. At the same time, through the unique optical design technology, a matching diffraction grating is set outside the QCL to form a resonator, and the tilt is controlled by electrical appliances. The world's first QCL module capable of generating arbitrary terahertz waves in the range of 0.42 to 2 THz at room temperature has been realized.
Endikasyon pou chanje frekans
Prensip pou chanje frekans: Travès lazè enfrawouj mitan-emèt nan yon QCL ki pa lineyè terahertz reflete nan yon griyaj difraksyon. Nan ka sa a, chanje frekans lan nan vag THz reyalize pa elektrik kontwole griyaj la diffraction ak chanje enklinasyon an.
Fond RD
Due to the different components contained in the sample to be tested, the frequency of terahertz waves that are easily absorbed will also be different. Using this characteristic, the research results are expected to be used for quality assessment and non-destructive analysis of samples. In addition, since terahertz waves are higher in frequency than the frequency band used by the high-speed communication standard "5G", this product is also expected to be used for the next generation of "6G" communication.
Nan 2018, Hamamatsu Photonics te devlope yon QCL ki pa lineyè terahertz lè li itilize teknoloji inik konsepsyon estrikti pwopòsyon an, lè l sèvi avèk konsepsyon anti-travèse doub gwo-eta enèji (AnticrossDAUTM). Sa a terahertz nonlinear QCL ka chanje frekans nan vag terahertz la ak iradyasyon li dapre konpozan ki genyen nan echantiyon an, ak Lè sa a, amelyore presizyon nan analiz dapre pousantaj la absòpsyon. Sepandan, kounye a pa gen okenn sous limyè semi-conducteurs lazè ki ka reyalize chanjman frekans nan yon sèl modil. Se poutèt sa, Hamamatsu Photonics te fè rechèch ak devlope frekans-chanje modil QCL yo.
Rezime reyalizasyon RD
In this research report, Hamamatsu Photonics analyzed the generation principle of terahertz waves in QCL, and optimized the internal structure using crystal growth technology and semiconductor process technology accumulated over the years. At the same time, the principle of terahertz wave propagation inside the QCL was also analyzed, and it was found that the connection between the top surface and the high{{0}}resistance silicon lens can improve the generation efficiency of terahertz waves and increase the output power to more than 5 times that of the past. Combining the unique optical design technology of Hamamatsu Photonics, and matching the QCL with a suitable diffraction grating, an efficient external resonator is formed, and then the inclination is changed by electrically controlling the diffraction grating, thereby realizing the world's first 0.42 A QCL module that generates terahertz waves of arbitrary frequencies in the 2THz range.
Rezilta etid sa a montre ke nan ka diferan frekans absòpsyon nan diferan konpozan nan echantiyon an yo dwe teste, lè l sèvi avèk yon modil chanje frekans lan ak iradyasyon etwat -vag terahertz yo tcheke to a absòpsyon nan chak eleman. ka amelyore dwòg, manje ak materyèl semi-conducteurs. evalyasyon kalite ak presizyon nan tès ki pa-destriktif. Anplis de sa, li sipoze aplike tou nan idantifikasyon materyèl polymère segondè -molekilè tankou plastik ki pa te fasil idantifye anvan. Apre sa, Hamamatsu Photonics ap kontinye etidye estrikti dissipation chalè QCL an pwofondè, vize reyalize operasyon ki estab ak kontinyèl nan vag THz. Li espere ke vag THz yo pral itilize nan domèn tankou astwonomi radyo pou obsève linivè a, ak vitès transmisyon done a pral rive nan dè santèn de gigabit pou chak segonn. Aplikasyon nan direksyon devlopman ultra-wo-vitès gwo-kapasite kout-kominikasyon san fil.
Nan tan kap vini an, Hamamatsu Photonics pral itilize tou teknoloji inik sistèm mikwoelektromekanik li yo (MEMS) pou retresi modil QCL jiska gwosè yon dwèt.
