LioniX Tsim Ib Qhov Ze-Infrared Ultra-Narrow Linewidth Tunable Laser

LioniX International, tus muab kev koom ua ke ntawm photonics thiab kev cai MEMS cov cuab yeej daws teeb meem, tsis ntev los no tau tsim ib qho ultra-luv kab dav tunable laser ntawm lub nti uas hais txog qhov nqaim ntawm qhov ze-infrared lub teeb, hauv kev koom tes nrog cov koom tes koom tes hauv REAP project. Nws tau piav qhia tias muaj kab dav dav ntawm 22 kHz, qhov sib txawv ntawm 45 nm, lub zog tso zis ntawm 5 dBm thiab SMSR ntawm -40 dB.
Hybrid kev koom ua ke ntawm sab nraud kab noj hniav vernier lasers
Lub laser no kuj zoo li yooj yim: lub semiconductor optical amplifier txuas nrog TriPleX® nti uas nkag ncaj qha rau hauv fiber ntau. Lub zog laser los ntawm kev sib xyaw ua ke ntse uas suav nrog lub lim dej vernier (vernier filter) thiab ob lub suab nrov micro-ring resonators siv rau ntawm lawv lub platform, thiab tseem suav nrog Mach-Zendel interferometer rau kev kho qhov tso zis sib txuas ua haujlwm.
Txhawm rau kom ntseeg tau tias thermal stability rau kev siv mus sij hawm ntev, lub laser tau teeb tsa nrog qhov tsis zoo ntawm qhov kub thiab txias coefficient thermistor mounted ntawm photonic integrated circuit thiab thermoelectric cooler tso rau hauv ib lub hnab 14-pin npauj npaim. Kev tswj cov cua kub, nrog rau lub wavelength thiab qhov tso zis tso zis, yog siv hluav taws xob tuned nrog ib qho ntawm lawv cov laser controllers, tsim los siv nrog cov kab noj hniav sab nraud.
Fast tuning hla ntau yam
Ntawm qhov nruab nrab wavelength ntawm 800 nm, lub cuab yeej muaj qhov tso zis siab tshaj plaws ntawm 5 dBm thiab qhov tsawg kawg nkaus sab hom tsis lees paub qhov piv ntawm -40 dB. Tom qab kuaj nws lub lag luam rau ntau tshaj ib hnub, cov khoom siv laser no qhia tau hais tias tsawg tsawg thiab qhov kub ntawm qhov kub ntawm 25 degrees. Qhov ntsuas lub teeb muaj qhov dav dav ntawm 22 kHz thiab qhov nrawm ntawm sub-kHz.
Lub Circuit Court tau tsim los siv nws qhov kev pabcuam 850 nm MPW, siv lub khob hliav qab waveguide kom meej txuas cov nti mus rau qhov nce thiab cov zis fiber ntau. Qhov tsis pom kev ntawm cov kev sib tshuam no tuaj yeem ua rau qis li 0.3 dB ntawm qhov nce thiab 0.4 dB ntawm sab fiber ntau. lawv TriPleX® platform kuj txhawb nqa ntsug waveguide cones, tab sis qhov no tsis yog siv rau hauv cov qauv no.
