- Abstract
- Recently, research interests in chiral photonics is rapidly increasing toward various applications including
display, sensors, optical communication and high quality optical cavity. Compared to the complex nano processed
photonic systems helicoidal arrangements of optical dielectric materials in chiral photonic structure allows easy
and inexpensive high quality optical photonic wavelength forbidden band structure which can be scalable and
used for practical applications. Furthermore, in contrast to the expensive nano-processed optical structure, which
is fixed and difficult to change properties due to the dependency of confirmed nano fabricated structure, chiral
photonic band structure and photonic properties can be tuned by changing chiral pitch length or effective optical
dielectric or structure deformation using of soft matters such as polymer and liquid crystals.
In this invited talk, we discuss the controlled deformation of chiral structure in various methods and advanced
functionalities of chiral photonic systems. In details, electrical tunability wavelength in broadband with stable
optical quality, polymer chiral template for 2D and 3D structure and in further reversibly stretchable chiral
photonic structure are discussed. By using of these high quality nano optical cavity properties and advanced
functionalities of easy structured chiral photonic structure we briefly introduce chiral photonic micro laser
emission which can be beyond OLED and QD emission. We also discuss the sufficiently hyper twisted helically
rotating system which allows negative inversion of slow axis along to the helical axis. In further, electrical
deformation of this hyper twisted chiral optical slow axis switching for ultra fast electro-optical switching will be
briefly explained.
