A novel DWDM interleaver scheme based on phased-array wavelength demultiplexer with multimode interf
[期刊论文] 作者：SiLu,YingbaiYan,GuofanJin,
来源：ChineseOpticsLetters 年份：2004
A novel integrated dense wavelength division multiplexing interleaver scheme is presented based on phased-array (PHASAR) wavelength demultiplexer with multimode interference (MMI) couplers. MMI-PHASAR interleaver with simple structure and c......

Freeform surfaces are difficult to manufacture due to their lack of rotational symmetry. To reduce the requirements for manufacturing precision, a design method is proposed for freeform reflective-imaging systems with low surface-figure-err......

In holographic encryption, double random-phase encoding in the Fresnel domain (DRPEiFD) is a prevalent encryption method because it is lensless and secure. However, noises bring adverse effects during decryption. In this letter, we introduc......
Tunable directional beaming assisted by asymmetrical SPP excitation in a subwavelength metallic doub

We present a design for tunable directional beaming through a subwavelength metallic double slit surrounded by dielectric surface-relief gratings. On-axis and off-axis beaming can be switched by controlling the incident angle to asymmetrica......
