A device and a method for aligning a laser unit to a waveguide unit. The method may include (a) placing the laser unit in a tested position in which the laser unit faces the waveguide unit;(b) supplying light, via a coupler of the waveguide unit, to an alignment waveguide of the waveguide unit; (c) receiving light emitted from the alignment waveguide; wherein the light was emitted as result of the supplying of the light; (d) determining whether the light emitted from the alignment comprises a spectral signature associated with an alignment unit of the laser unit; and (e) estimating whether the laser unit is aligned to the waveguide unit based on the determining of step (d).

Method and device for aligning a laser and a waveguide

The disclosure describes a method for assembling an optical coupler, the method may include (a) inserting optical fibers of an array of optical fibers through an array of openings of a mount of the optical coupler so that tips of the optical fibers pass through the array of openings of the mount and reach an adaptor; wherein the array of openings of the mount exhibit a first positioning accuracy; (b) using the adaptor to position the tips of the optical fibers at predefined locations, at a second positioning accuracy that is higher than the first positioning accuracy; (c) fixing the tips of the optical fibers to the mount while maintaining the tips of the optical fibers at the predefined locations; and (d) detaching the mount from the adaptor.

Optical coupler and a method for assembling an optical coupler

A method for determining a spatial relationship between an optoelectronic chip and an optical mount, the method may include temporarily filling, by a liquid, a gap formed between a lens of the optical mount and the optoelectronic chip, while the optical mount contacts the optoelectronic chip; inspecting an optical component of the optoelectronic chip through the lens and through the liquid that fills the gap; and determining the spatial relationship between the optoelectronic chip and the optical mount based on the outcome of the inspecting of the optical component.
