Abstract: 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).

Abstract: A method for operating multiple chip regions. The method includes aligning the multiple chip regions using first wavelength band signals, and conveying transmission signals of a second wavelength band signals. The multiple chip regions may be without a second wavelength band transmitter and include a path for receiving the second wavelength band signals from another chip.

Abstract: A method for aligning a laser unit to a waveguide unit, the method may comprise placing the laser unit in a tested position in which the laser unit faces the waveguide unit; supplying light, via a coupler of the waveguide unit, to an alignment waveguide of the waveguide unit; receiving light reflected from the alignment waveguide; wherein when aligned to the waveguide unit, an alignment unit of the laser unit reflects toward the alignment waveguide light having a spectral signature of the alignment unit; and wherein when misaligned to the waveguide unit, the laser unit is configured to reflect light without the spectral signature of the alignment unit towards the alignment waveguide; determining whether the light reflected from the alignment waveguide comprises the spectral signature associated with the alignment unit of the laser unit; wherein the alignment waveguide exhibits a frequency selective response that has the spectral signature; wherein the frequency selective response differs from a reflection from a mirror, wherein other frequencies than the frequency selective response are not returned by the mirror towards the alignment unit and then to the waveguide unit or at least are not returned by the mirror towards the alignment unit and then to the waveguide unit, without being significantly attenuated, thereby reducing or eliminating the reflected radiation from the mirror towards the waveguide unit; and estimating whether the laser unit is aligned to the waveguide unit based on the determining.
