Laser yihuta cyane, ingana n'umutwe w'urutoki, ifite imikorere myiza cyane

Umusaruro uri hejurulaser yihuta cyaneingano y'urutoki

Nk’uko inkuru nshya yasohotse mu kinyamakuru Science ibivuga, abashakashatsi bo muri Kaminuza ya City University ya New York bagaragaje uburyo bushya bwo gukora imikorere myizalaser yihuta cyanekuri nanophotonics. Iyi mode ntoya ifunzelaseritanga urukurikirane rw'urumuri rugufi cyane mu gihe cy'amasegonda ya femto (trillionths of a segonda).

Uburyo bwa Ultrafast-lockedimirasire ya laserbishobora gufasha guhishura amabanga y’igihe cyihuse cyane mu bidukikije, nko gushinga cyangwa gucika kw’imigozi ya molekile mu gihe cy’ibikorwa bya shimi, cyangwa gukwirakwiza urumuri mu buryo butunguranye. Umuvuduko wo hejuru, imbaraga z’amajwi menshi, hamwe n’uburyo bwagutse bwo gukwirakwiza imirasire ya lasers ifunze neza nabyo bituma ikoranabuhanga ryinshi rya photon, harimo amasaha y’atomu y’urumuri, amashusho y’ibinyabuzima, na mudasobwa zikoresha urumuri mu kubara no gutunganya amakuru.

Ariko laser zigezweho cyane zifunze neza ziracyahenze cyane, sisitemu za mudasobwa zisaba ingufu nyinshi kandi zikoreshwa muri laboratwari gusa. Intego y'ubushakashatsi bushya ni uguhindura iyi sisitemu ifite ubunini bwa chip ishobora gukorwa ku bwinshi no gushyirwa mu rwego rw'ikoranabuhanga. Abashakashatsi bakoresheje urubuga rw'ibikoresho rushya rwa lithium niobate (TFLN) kugira ngo bashyireho neza kandi bagenzure neza imivuduko ya laser binyuze mu gukoresha ibimenyetso by'amashanyarazi byo hanze ya radio. Itsinda ryahuje ubwiyongere bwa laser bwinshi bwa semiconductors zo mu cyiciro cya III-V hamwe n'ubushobozi bwiza bwo gushushanya pulse bwa TFLN nanoscale photonic waveguides kugira ngo bakore laser itanga imbaraga nyinshi za watts 0.5.

Uretse ingano yayo nto, ifite ingano y'urutoki, iyi laser iherutse kwerekwa ifite uburyo bushya bwo gufunga isura igaragaza imiterere myinshi iyo laser isanzwe idashobora kugeraho, nko kuba ishobora guhindura neza umuvuduko w'isubiramo ry'umuvuduko w'ingufu ku rugero runini rwa megahertz 200 binyuze mu guhindura gusa umuvuduko w'ipompe. Itsinda ryizeye kugera ku isoko ry'ingufu rihoraho, rikoresha ingano ya chip, binyuze mu guhindura imiterere ikomeye ya laser, ari ingenzi cyane mu kumenya neza. Harimo gukoresha telefoni zigendanwa mu gusuzuma indwara z'amaso, cyangwa gusesengura E. coli na virusi ziteje akaga mu biribwa no mu bidukikije, no gutuma habaho uburyo bwo kugenda mu gihe GPS yangiritse cyangwa idafite aho ihuriye.
