Rofea muaj ib pab pawg kws tshaj lij, kev tshawb fawb uas tau xa ntau lub voj voog kho qhov muag thiab cov modules rau kev siv lag luam. Piv txwv li, cascaded MZ modulator, cascaded phase modulator, thiab array phase modulator yog raws li nram no:
1, Cascaded MZ modulator & cascaded theem modulator
Cascaded MZ modulator Cascaded theem modulator
Tus cascaded MZ modulator sib xyaw ua ke ob lub MZ modulators, uas muaj kev ploj mus siab ntawm 50dB, 3dB bandwidth ntawm 10GHz. Thiab tus cascaded theem modulator muaj cascaded modulation thiab bias controller, 3dB bandwidth tuaj yeem hloov kho.
2,1 * 4 theem modulator
Tus 1 * 4 theem modulator sib xyaw ua ke 4 theem modulator thiab cascaded Y-ceg splitter rau hauv ib lub voj voog, uas muaj kev ua tau zoo hauv laser phased array daim ntawv thov.
Peb lub tuam txhab tau koom nrog kev tsim kho thiab tsim cov khoom lag luam optoelectronic tau kaum xyoo, txais tos los sab laj txog kev kho kom haum rau cov khoom lag luam optoelectronic. Tsis tas li ntawd, peb lees txais cov lus txib khoom lag luam, tiv tauj peb kom paub ntau ntxiv.
