Abstract

The invention discloses multi-channel integrated optical couplers and a method for manufacturing the multi-channel integrated optical couplers. Optical coupler units are arranged on the same side of a substrate. One-to-one correspondence of organic electroluminescence components and organic photosensitive components can be achieved without increasing the areas of the optical coupler units. All the independent optical couplers do not need independently packaging, and therefore the level of integration is high. Lighttight isolation columns are arranged between the optical coupler units, light signal crosstalk between adjacent optical coupler units does not exist, and therefore the interference resistance performance is good. All the components are made of organic materials, and therefore the multi-channel integrated optical couplers have flexibility and are light, thin, small in size and wide in application range. Due to the adoption of an organic thin-film device manufacturing technology, all the optical coupler units are arranged on the same side of the substrate, and accordingly the level of integration is high; furthermore, the lighttight isolation columns are arranged between the optical coupler units, light signal crosstalk between the adjacent optical coupler units does not exist, and therefore the interference resistance performance is good; an adopted production process of existing organic thin-film devices is mature and low in manufacturing cost.

Description

Technical field [0001] The invention relates to the field of optoelectronics, in particular to a multi-channel integrated optocoupler device and a preparation method thereof. Background technique [0002] An optocoupler device is an optoelectronic device that can transmit signals when it is usually used for electrical isolation. It can convert a signal into an optical signal, and then an optical signal into another detectable signal. Generally, it includes at least three important functional components: functional components that can convert electrical signals into light and output light, and Electrical insulation and isolation components that can transmit light and photosensitive functional components that take optical signals as input and output as detectable signals. The most commonly used optocoupler devices, such as figure 1 As shown, an electroluminescent component A is used to convert an electrical signal into an optical signal, and a photosensitive component B, such as a...
