Abstract
Methods and systems for down-conversion of high frequency signals in millimeter-wave (mm-wave) communications and for up-conversion of high frequency signals in millimeter-wave (mm-wave) communications. A quantum dot multi-wavelength laser (QD MWL) source generates an optical signal comprising of a plurality of optical channels and allows flexible selection of the optical channels which can be used to generate and process RF signals in higher frequency bands of mm-wave spectrum including K-band, Ka-band V-band, W-band encompassing all 3GPP NR FR2 bands and even THz range depending on the channel spacing.
