Abstract
Polymers are promising materials for fabricating photonic integrated waveguide devices. Versatile functional devices can be manufactured using a simple process, with low cost and potential mass-manufacturing. This paper reviews the recent progress of polymer photonic integrated devices fabricated using the UV imprinting technique. The passive polymer waveguide devices for wavelength filtering, power splitting, and light collecting, and the active polymer waveguide devices based on the thermal-optic tuning effect, are introduced. Then, the electro-optic (EO) modulators, by virtue of the high EO coefficient of polymers, are described. Finally, the photonic biosensors, which are based on low-cost and biocompatible polymer platforms, are presented.
Highlights
Polymers, which have the advantages of low cost, flexile tuning of their refractive index, and a designable function with synthetization at the molecular level, have promising applications for fabricating photonic integrated waveguide devices [1,2,3,4,5]
The arrayed waveguide grating (AWG) with the similar function of diffraction grating can be used as a wavelength multiplexer or demultiplexer
These results show that the UV soft imprinting technique has the capability to fabricate three-dimensional functional photonic devices [36]
Summary
Polymers, which have the advantages of low cost, flexile tuning of their refractive index, and a designable function with synthetization at the molecular level, have promising applications for fabricating photonic integrated waveguide devices [1,2,3,4,5]. Several papers have been presented to review the progress of the imprinting technique comprehensively, including the imprinting craft, the material requirement, and the fabricated function components [23,24,25,26,27,28,29,30,31,32,33]. The recent progress of polymer photonic waveguide devices fabricated using the imprinting technique, and their applications are reviewed.
