Light source using laser diodes

#1. Technical Field

#The present disclosure relates to light sources and, particularly, to a light source using laser diodes.

#2. Description of Related Art

#Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure.

#FIG. 1 is a top view of a light source, according to an exemplary embodiment.

#FIG. 2 is a partial side view of the light source of FIG. 1.

#FIGS. 1 and 2 show a light source 10 according to an embodiment. The light source 10 includes a base 11, a waveguide 12, two laser diodes 13, a substrate 14, a first bonding layer 15, and a second bonding layer 16.

#The base 11 can be a printed circuit board (PCB) and includes a first surface 111 such as a top surface. The base 11 forms two pads 112 on the first surface 111.

#The waveguide 12 is a planar waveguide and includes a first input branch 121, a second input branch 122, and an output section 123. Each of the first input branch 121 and the second input branch 122 has an input end 124. The output section 123 has an output end 125. The first input branch 121 includes a first section 1211 having the input end 124 and parallel with the output section 123, and a second input section 1212 extending from an end of the first input section 1211 opposite to the input end 124 to an end of the output section 123 opposite to the output end 125. The second input branch 122 includes a third section 1221 having the input end 124 and parallel with the output section 123, and a fourth input section 1222 extending from an end of the third input section 1221 opposite to the input end 124 to the end of the output section 123 opposite to the output end 125.
