Abstract

The invention discloses an asymmetric lens and optical devices. An optical axis center of the asymmetric lens is offset from a geometric center of a lens carrier by a predetermined distance, the optical axis center and each coupling surface of the lens carrier are respectively offset by a preset vertical distance, and the coupling surface is used for being coupled with an optical path substrate tobe coupled. The asymmetric lens can be applied to a variety of the optical devices or a plurality of application scenarios, have higher versatility and be advantageous for large-scale automated production.

Description

【Technical field】 [0001] The invention relates to the field of lens structures, in particular to an asymmetric lens and an optical device. 【Background technique】 [0002] The full name of the optical module is Optical Transceiver, which is the core component of the optical communication system and completes the optical-electrical / electrical-optical conversion of optical signals. The optical transceiver integrated module consists of two parts: the receiving part and the transmitting part. The receiving part realizes the light-to-electricity conversion, and the transmitting part realizes the light-to-light conversion. The working process of the transmitting part: the electrical signal of a certain code rate is input and processed by the internal driver chip to drive a semiconductor laser LD (Laserdriver, abbreviated as LD) or a light emitting diode LED (Light Emitting Diode, abbreviated as LED) to emit a corresponding rate of modulation The optical signal has an automatic op...
