Abstract :
We report here large-area broadband photonic crystal membrane reflectors (MRs) on glass substrates based on laser interference lithography (LIL) patterning and elastic stamp membrane transfer printing techniques. High-reflectivity broadband MRs on glass were realized with measured reflectivity of 95% around 1300 nm and a bandwidth of about 100 nm. Large-area nanopattern uniformity was experimentally verified with measured reflectivity from multiple locations of the large-area MRs. The work could lead to fabrication of the large-area high-performance MR at low cost with high throughput. The reflectors can be used in many types of optoelectronic and photonic devices.
