“…The single mode condition for the waveguide structure is essential for any integrated opto-electronic device to sustain the fundamental mode of propagation for strong optical confinement and efficient coupling with external optical fibers without intermode interference. A hybrid numerical-analytical design methodology for obtaining single mode condition in ridge waveguides with geometries larger than the wavelength of guided light has been presented in our previous work [29]. We design a ridge waveguide structure following our design methodology and perform finite difference time domain (FDTD) simulations in OptiFDTD 32-bit tool to validate the design.…”

“…Knowing the parameters related to the active region and assuming the structure including the waveguide, one can calculate the parameters of the ridge waveguide. The AlN cover layer, with the index of refraction of 2.165 can be assumed to be effectively infinite because the evanescent waves will not penetrate very far into the layer [71]. The guiding layer or core is AlGaN/GaN/AlGaN layers.…”

“…Desta forma, é necessário controle adequado da deposição que deve ocorrer em curto período [12], conforme Figura 23, que mostra que maiores tempos de deposição conduzem a maiores perdas por propagação (sobretudo para os guias mais estreitos), com consequências no ganho, conforme será visto no item a seguir. A escolha desse simulador foi motivada pelos resultados de trabalhos desenvolvidos na área da Óptica Integrada [28][29][30] e a sua versão 32bits [31] ser gratuita para utilização.…”
