Embodiment approach 1

[0025] Such as Image 6 The shown lens adjustment structure of the present invention, the lens adjustment structure is divided into two pieces, and is composed of the lens adjustment structure upper part 205 and the lens adjustment structure lower part 206. The lower end surface of the lens adjustment structure upper part 205 is an inclined plane, and the lens adjustment structure lower part 206 has a slope matching the lower end surface of the lens adjustment structure upper part 205, the lens adjustment structure upper part 205 and the lens adjustment structure lower part 206 contact through the slope surface, the top of the lens adjustment structure is provided with a lens 104, and the lens adjustment structure is connected with the lens 104 in the horizontal direction movement to realize the adjustment of the lens 104 in the X-axis and Y-axis directions; the upper part 205 of the lens adjustment structure moves up and down along the slope of the lower part 206 of the lens a...

Embodiment approach 2

[0027] Such as Figure 7-9 The light-emitting device of a signal channel unit that adopts the lens adjustment structure of the present invention is shown based on a carrier substrate 101, a heat sink 102 is arranged on the signal channel unit, a semiconductor laser chip 103 is arranged on the top of the heat sink 102, and a semiconductor laser chip 103 is arranged on the top of the heat sink 102. The laser chip 103 is used as a light source for emitting modulation signals. The heat sink 102 is used to make the position of the semiconductor laser chip 103 reach a specific height and play a role in heat dissipation. The lens adjustment structure in Embodiment 1 is also provided. The top of the lens adjustment structure The provided lens 104 is used to convert the light emitted by the semiconductor laser chip 103 into parallel light or converging light, and the heat sink 102 and the lens adjustment structure are sequentially arranged on the carrier substrate 101 along the light pa...

Embodiment approach 3

[0029] Such as Figure 10-11 The light-emitting device of the multi-signal channel unit that adopts the lens adjustment structure of the present invention as shown is based on a carrier base

[0030] Based on the board 101, several signal channel units described in Embodiment 2 are arranged in parallel on its upper part, and the center-to-center distance a of the semiconductor laser chips of two adjacent signal channel units is equal. At present, the distance between the signal channels of the light-emitting device is usually less than 1mm, but it can also be set to a width different from the existing calculation, and the lens width b is usually 0.7mm, but it can also be set to a different width from the existing calculation, because the present invention The light-emitting device in the embodiment adopts the lens adjustment structure in Embodiment 1, so it can meet the requirement that the distance between signal channels is less than 1mm, realize the parallel mode of multipl...

Abstract

The invention relates to the technical field of optical communication, in particular to an optical device. A lens adjustment structure is composed of an upper portion of lens adjustment structure anda lower portion of lens adjustment structure, a lower end face of the upper portion of lens adjustment structure is an inclined plane, the lower portion of lens adjustment structure is provided with an inclined plane matching the lower end face of the upper portion of lens adjustment structure, the upper portion of lens adjustment structure is in contact with the lower portion of lens adjustment structure through the inclined plane, a lens is arranged at the top of the lens adjustment structure, and the upper portion of lens adjustment structure, the lower portion of lens adjustment structureand the lens have the same width. The lens adjustment structure provided by the invention can greatly save the space in the X direction and meet the spacing requirements between signal channels. The above-mentioned lens adjustment structure is adopted in a light transmitting device provided by the invention, a multi-signal channel parallel manner can be realized to improve the overall transmissionrate, and meanwhile the miniaturized package requirement of 100 Gbps (4*25 G) or 400 Gbps (8*50 G) light transmitting device can be met.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical device. Background technique [0002] As the transmission speed of information technology is updated day by day, optical communication technology has been widely valued and applied, and the application of optical devices has also increased. In the existing optical emitting devices, the transmission rate of high-speed signals has increased from hundreds of Mbps to dozens or even above. Hundred Gbps. In light-emitting devices, multiple signal channels are usually used in parallel to increase the overall transmission rate. As the package size becomes smaller and smaller, the number of signal channels increases, and the distance between signal channels becomes smaller and smaller. This makes the lens Coupling and securing are increasingly difficult. [0003] Such as Figure 1-5 As shown, at present, most of the traditional lens adjustment structures adopt U...
