We propose a three-dimensional waveguide structure for the realization of mode-selective switches, where the high-order spatial modes of a few-mode waveguide can be switched to various single-mode waveguides with thermo-optically controlled vertical asymmetrical directional couplers.To demonstrate the idea, we design and fabricate two specific devi

The uncontrolled rectifier and controlled rectifier which use fixed switching frequency control strategy are applied usually during the working of a high-power high- speed permanent magnet generator (HSPMG).Even for the controlled rectifier, it will generate harmonics.The electromagnetic performance of the HSPMG is also affected by these harmonics.
Myopia has significantly risen in East and Southeast Asia, and the pathological outcomes of this condition, such as myopic maculopathy and optic neuropathy linked to high myopia, have emerged as leading causes of irreversible vision loss.Addressing this issue requires strategies to reduce myopia prevalence and prevent progression to high myopia.Enc
