Abstract
An optical subassembly includes an opto-electronic device, an optics block and a spacer, separate from the optics block and providing spacing between the opto-electronic device and the optics block. The opto-electronic device, the optics block and the spacer are aligned and bonded together. This subassembly is particularly useful when coupling light between the opto-electronic device and a fiber. The optical subassembly may also include an opto-electronic device, an optics block and a sealing structure surrounding the opto-electronic device. The opto-electronic device, the optics block and the sealing structure are aligned and bonded together.
Claims15
A system comprising:
- a mount supporting an opto-electronic device;
- an optics block having at least one optical element;
- and
- a spacer providing spacing between the opto-electronic device and the optics block, the spacer surrounding the opto-electronic device, the spacer and the optics block protecting the opto-electronic device from environmental factors, wherein at least two of the mount, the optics block and the spacer are aligned and secured on a wafer level prior to dicing.
A system comprising:
- an opto-electronic device on a first substrate;
- an optics block having at least one optical element thereon and being transparent to light relayed between an optical waveguide and the opto-electronic device;
- and
- a second substrate receiving the opto-electronic device therein, wherein at least two of the optics block, the first substrate and the second substrate seal the opto-electronic device from environmental factors.
