Abstract
An optical module includes a circuit board, an optical fiber, an optical fiber monitoring chip, a laser chip, a laser driving chip and a lens assembly. A bottom surface of the lens assembly is covered above the laser chip and the optical monitoring chip. A groove is on a top surface of the lens assembly. A bottom of the groove protrudes to form a first interface and a second interface. The laser chip is configured to emit light. The first interface is configured to reflect the emitted light to obtain first reflected light. The second interface is configured to reflect a portion of the first reflected light to obtain a second reflected light and refract another portion of the first reflected light to obtain a first refracted light. The second reflected light is transmitted to the optical monitoring chip. The first refracted light is transmitted to the optical fiber.
