Laser module allowing direct light modulation and laser display employing the same |
摘要 |
Provided are a laser module allowing direct light modulation and a laser display employing the laser module. The laser module may include a semiconductor chip, a Volume Bragg Grating (VBG), a pump laser and a non-linear optical element. The semiconductor chip includes an active layer generating light of primary wavelength and a reflective layer providing the generated light to a cavity and reflecting the light within the cavity. The VBG may output light repeatedly reflected between the reflective layer and the VBG. The non-linear optical element disposed outside a cavity between the semiconductor chip and the VBG may convert the light of a first wavelength emitted from the active layer into light of a second wavelength different from the first wavelength. The laser module having the above-mentioned construction uses an external cavity laser and a non-linear optical element to achieve direct light modulation.
