An optical device, comprising:
- a plurality of LDs each emitting light with a specific color, each of said LDs being mounted on a corresponding sub-mount of a plurality of sub-mounts;
- a plurality of fibers each propagating said light individually;
- a substrate including a first alignment substrate and a second alignment substrate, said first alignment substrate provided with a first type of grooves, each of said first type of grooves setting one of fibers therein individually, said second alignment substrate provided with a second type of groove setting said fibers collectively therein;
- and
- a base with said sub-mounts, said first alignment substrate and said second alignment substrate mounted thereto,
- wherein said first alignment substrate and said second alignment substrate define a hollow therebetween, said fibers extending unrestrained and wiggly within in said hollow.
