Abstract Optical Tamm states (OTS) are confined optical modes that can occur at the interface between two highly reflective structures. However, due to strong reflectance required, their implementation with processable and metal-free flexible materials has proven challenging. Herein, we develop first structure supporting OTS based only on organic polymeric materials, demonstrating a photonic pl...

Vertical-cavity surface-emitting lasers (VCSELs) have been widely used in consumer electronics, light detection and ranging, optical interconnects, atomic sensors, so on. In this paper, a VCSEL with the surface metastructure like one-dimensional high-contrast grating (HCG), based on HCG-DBR vertical cavity, was first designed fabricated. The polarization characteristic of HCG-VCSEL were experim...

In a future massively parallel computing system with many processor elements (PEs), interconnection among the PEs would be a bottle-neck for improving system performance especially in the power consumption. For a highly parallel system, conventional electrical interconnection requires many high-speed switches that consume much electrical power, restricting the system performance. Concerning thi...

Laser diodes, in general, are sensitive to optical feedback, especially with regard maintaining single-frequency operation. Until now, however, the feedback sensitivity of high-power devices such as distributed Bragg reflector (DBR) tapered laser diodes has not been investigated quantitative detail. In this paper, we analyze impact very weak between <mml:math xmlns:mml="http://www.w3.org/1998/M...
