摘要

Ultracompact wave plate (UWP) will be one of the key elements in future all-optical photonic integrated circuits (PICs).In this paper, we propose UWPs based on periodic dielectric waveguides (PDWs) with air holes in conventional dielectric waveguides. The mode characteristics (for both TE and TM) and birefringence of PDWs are calculated by plane wave method (PWM). The transmission efficiencies and phase changing of TE and TM waves in PDW are obtained by finite-difference time-domain (FDTD) scheme. Based on the PDWs, the quarter-wave plates (QWPs) and halfwave plates (HWPs) are designed. Calculating results show that the proposed PDW has large birefringence (Δn>1) and can introduce 2π phase difference with a short length being less than λ. The size of low order UWPs are compact. The transmission efficiency of PDW is improved by taper structure. Based on the taper PDW, ultra-wide band (>100 nm) achromatic QWP is designed. Profiting from the waveguide guiding, the UWPs have low beam divergence and can be easily integrated with other photonic components. The UWPs have many potential applications in future PIC systems such as optical communications, optical measurements and sensors.
