摘要： According to an aspect, there is provided an optical memory unit. The optical memory unit comprises first and second slave lasers configured, respectively, to output first and second laser beams having a first frequency when injection-locked with first and second injection laser beams having the first frequency. The first and second slave lasers are configured to be mutually coupled and the optical memory unit is configured so that an optical path length between the first and second slave lasers corresponds to a phase shift of at the first frequency. Said injection-locking enables maintaining, at a time, one of two steady states when the first and second injection beams have the same amplitude and phase while switching between the two steady states is enabled by introducing an amplitude and phase or amplitude and polarization perturbation component to at least one of the first and second injection laser beams.

摘要： Described is an optical amplifier comprising a polarization beam splitter (PBS) (303) arranged to receive an optical beam and to split it into a first beam and a second beam, the first beam being transverse magnetic (TM), the second beam being transverse electric (TE); a first amplifier channel (350) arranged to receive the first beam and to amplify it; a second amplifier channel (351) arranged to receive the second beam and to amplify it; and a polarization beam combiner (PBC) (304) arranged to combine an output beam of the first amplifier channel (350) and an output beam of the second amplifier channel (351). The first amplifier (350) channel comprises: (i) a TM-to-TE-mode converter (352) arranged to receive the first beam and to convert it from TM to TE; and (ii) a first amplifier arrangement (305, 306, 307) arranged to receive an output beam of the TM-to-TE-mode converter and to apply an adjustable amplification to it. The second amplifier channel comprises: (i) a second amplifier arrangement (308, 309, 310) arranged to receive the second beam and to apply an adjustable amplification to it; and (ii) a TE-to-TM-mode converter (353) configured to convert an output beam of the second amplifier arrangement from TE to TM. This may result in an optical amplifier with decreased polarization dependent loss.
