摘要: We propose a trench assisted long-period-waveguide-grating (LPWG) design for flattening the gain spectrum of erbium doped waveguide amplifier. The structure consists low index in cladding region. modes have been evaluated by transfer matrix method and transmission characteristics long period grating simulated using coupled mode theory. has utilized to equalize amplifier desired wavelength range. Using present we achieved 18.5 ± 0.96 dB 35 nm wide band (1526–1561 nm). numerically studied effect various parameters on LPWG, order optimize C-band an
