WebOct 31, 2024 · Abstract: In this work, we theoretically investigate the L3 cavity with three missing holes in the center. The Photonic cavities have an ultra-low index contrast and are fabricated by SiO 2 /ZrO 2 or SiO 2 /TiO 2 in which the refractive index varies in the range of 1.51 to 1.58 at λ =1.55 μm. WebMay 8, 2024 · The H1 and L3 PhC nanocavities cause a shift of 234 pm and 269 pm of cavity resonance wavelengths, respectively. Generally, gases are yet detectable by both types of cavities because their quality factors are large enough (\gg 10^ {5}).
WebL3 cavity, illustrating high intrinsic Q. (c) SEM of two-L3-cavity system, with phase detuning between the cavities. Each cavity is tuned (S 1 ¼ 0:15a) for high intrinsic Q. (d) Mul-tiple EIT-like system with three L3 cavities. The green spots indicate the focused pump beams used for thermo-optic tuning. WebAfter adding these new structures and their first principles Q factors to the training dataset, the above process is repeated. As an example, a standard silicon-based L3 cavity is optimized by this method. A cavity design with a high Q factor exceeding 11 million is found within 101 iteration steps and a total of 8070 cavity structures.
WebNov 14, 2016 · A typical mechanical configuration of a DR loaded cavity is shown in Figure 1. It is well known in practical high Q DR cavity design that the ratio of cavity height (Cty_H) to dielectric resonator thickness (DR_t) should be around 3 and that of cavity diameter (Cty_D) to dielectric diameter (DR_OD) should be greater than 1.5.
