Okwu Mmalite nke Laser Na-ewepụta Edge (EEL)

Okwu Mmalite nke Laser Na-ewepụta Edge (EEL)
Iji nweta mmepụta laser semiconductor nwere ike dị elu, teknụzụ dị ugbu a bụ iji usoro mwepụta n'ọnụ. Resonator nke laser semiconductor nke na-ewepụta n'ọnụ nwere elu nkewa nke kristal semiconductor, a na-ewepụtakwa ìhè mmepụta site na nsọtụ ihu nke laser ahụ. Laser semiconductor nke nwere akụkụ-emission nwere ike nweta ike dị elu, mana ebe mmepụta ya bụ elliptical, àgwà nke ogwe ahụ adịghị mma, a ga-agbanwekwa ọdịdị ogwe ahụ site na sistemụ ịkpụzi ogwe.
Ihe osise a na-egosi nhazi nke laser semiconductor na-ewepụta n'akụkụ. Oghere anya nke EEL dị n'akụkụ elu nke mgbawa semiconductor ma na-ewepụta laser n'ọnụ nke mgbawa semiconductor, nke nwere ike ime ka mmepụta laser pụta na ike dị elu, ọsọ dị elu na obere mkpọtụ. Agbanyeghị, mmepụta ogwe laser site na EEL na-enwekarị akụkụ obe nke eriri asymmetric na nnukwu ọdịiche akụkụ, arụmọrụ njikọ ya na eriri ma ọ bụ ihe ndị ọzọ dị n'ime anya dị ala.

Mmụba nke ike mmepụta EEL na-ebelata site na mkpokọta okpomọkụ mkpofu na mpaghara na-arụ ọrụ na mmebi anya na elu semiconductor. Site n'ịbawanye mpaghara nduzi ebili mmiri iji belata mkpokọta okpomọkụ mkpofu na mpaghara na-arụ ọrụ iji melite mgbasa okpomọkụ, ịbawanye mpaghara mmepụta ìhè iji belata njupụta ike anya nke ìhè iji zere mmebi anya, enwere ike nweta ike mmepụta nke ruru ọtụtụ narị milliwatts na nhazi nduzi ebili mmiri otu transverse.
Maka ntuziaka waveguide 100mm, otu laser nke na-ewepụta n'ọnụ nwere ike nweta ọtụtụ watts nke ike mmepụta, mana n'oge a, ntuziaka waveguide dị ọtụtụ ụdị na mbara nke mgbawa ahụ, oke akụkụ nke ìhè wave ahụ na-erukwa 100:1, nke chọrọ usoro nhazi ogwe dị mgbagwoju anya.
N'echiche na ọ dịghị ihe ọhụrụ a na-ahụ na teknụzụ ihe onwunwe na teknụzụ uto epitaxial, ụzọ kachasị mma isi melite ike mmepụta nke otu semiconductor laser chip bụ ịbawanye obosara nke mpaghara ọkụ nke chip ahụ. Agbanyeghị, ịbawanye obosara nke stripe ahụ dị elu nke ukwuu dị mfe imepụta oscillation ụdị dị elu na oscillation yiri filament, nke ga-ebelata nha nha nke mmepụta ìhè nke ukwuu, ike mmepụta anaghịkwa amụba n'otu nha na obosara stripe ahụ, yabụ ike mmepụta nke otu chip dị oke oke. Iji melite ike mmepụta nke ukwuu, teknụzụ array na-abata. Teknụzụ ahụ na-ejikọta ọtụtụ nkeji laser na otu substrate ahụ, nke mere na nkeji na-ewepụta ìhè ọ bụla dị ka usoro otu akụkụ na ntụziaka axis dị nwayọ, ma ọ bụrụhaala na ejiri teknụzụ nkewapụ anya kewapụ nkeji na-ewepụta ìhè ọ bụla na usoro ahụ, ka ha wee ghara itinye aka na ibe ha, na-emepụta lasing multi-aperture, ị nwere ike ịbawanye ike mmepụta nke chip dum site na ịbawanye ọnụọgụ nke nkeji na-ewepụta ìhè agbakwunyere. Mkpọ laser semiconductor a bụ ihe e ji laser array (LDA) mee, nke a makwaara dịka ihe e ji laser semiconductor mee.
