Disclosed is an optical module that improves optical coupling efficiency. Embodiments of the present invention provide an optical module including a first photonic device comprising a first emitting surface emitting an optical signal having a predetermined wavelength and intensity; a second photonic device comprising a first incident surface where the optical signal having the predetermined wavelength is incident; and a first intermediate layer comprising a first receiving surface receiving an optical signal delivered from the first photonic device and a first transmitting surface transmitting an optical signal to the outside and formed with a material having at least one of predetermined physical, mechanical, thermal, and optical properties between the first emitting surface and the first incident surface for transmission of an optical signal passing through the first receiving surface and the first transmitting surface.

A node comprises an FSP, a first FRU, a second FRU, and a controller. The FSP has a first connector having first port pairs and a second connector having second port pairs, a second port pair is optically coupled to at least one first port pair. The first FRU has third port pairs and a third connector coupled to the first connector. The second FRU has fourth port pairs and a fourth connector coupled to the second connector. The controller comprises a processor and a memory storing an FSP map and instructions, including: receive a first association between a third port pair and one of the first connector and the second connector; validate the first association; generate an FRU map based on the first association and the FSP map; update a mode type for each second association; receive a service activation request; and cause an FRU to activate the service.

Apparatuses, systems and methods for optical coupling, optical integration, electro-optical coupling, and electro-optical packaging are described herein. Optical couplers may comprise various optical elements (e.g., mirrors as described herein) to relax optical assembly requirements and improve producibility. Optical couplers may improve fiber-to-chip, fiber-to-fiber and chip-to-chip optical connection. Optical couplers and optical components may be used to improve integration of, connection of, and/or packaging of optical systems and/or components with electrical systems and/or components.

Passive alignment and connection between a fiber array and a plurality of optical waveguides terminating along an edge of a photonic IC is provided by a controlled mating between V-grooves formed in a fiber support substrate and alignment ridges formed to surround waveguide terminations along an edge of a photonic IC. The V-grooves of the fiber support substrate are spaced to define the same pitch as the waveguides on the photonic IC, with the height and width of the alignment ridges formed to engage with the V-grooves upon mating of the fiber support substrate with the photonic IC. The individual fibers are positioned within associated V-grooves such that their endfaces are retracted from a proximal end portion of the support structure. It is this proximal end portion that mates with the alignment ridges on the photonic IC.
