THE SMART TRICK OF SLOT432 THAT NO ONE IS DISCUSSING

Before the deposition in the Er:Al2O3 Lively material, the coupling circuit, i.e., the strip waveguides, the mode transition tapers as well as mode converters were lined which has a 800 nm thick layer of hydrogen silsesquioxane (HSQ, n ~1.45) to avoid their coating While using the active materials, as proven in Fig. 1. The HSQ cladding was dep
