Abstract

Abstract

The advantages of organic lasers with DFB distributed feedback structures have attracted much attention, however, there are few reports on the principle of multi-beam organic lasers using high-order Bragg feedback. Different from single-waveguide or single-beam lasers implemented by low-order Bragg feedback in the past, high-order Bragg feedback is introduced into a planar organic semiconductor waveguide to produce red and blue multi-beam organic lasers in this paper. Using a fourth-order Bragg feedback and PVK:DCJTI film, a three-beam red laser is realized with an exit angle of ±53° and 0.5°. A four-beam blue laser is implemented using a fifth-order Bragg feedback and PS:DSA-ph film with exit angles of ±18° and ±75°. The relationship between higher-order Bragg grating feedback and device characteristics is studied by combination of plane waveguide and grating coupling. The results show that the theoretically calculated beam coupling angle is consistent with the actual test, which provides guidance for the design of multi-beam organic laser devices to some extent.
