Electro-absorption optical modulator including ground shield

A wideband electro-absorption modulating (EAM) device is configured to include a ground shield that functions to minimize the spread of an applied AC voltage beyond the limits of the modulator's electrode. The ground shield includes a grounding electrode disposed in a spaced-apart relationship with the modulator electrode along the ridge of the EAM structure, and a grounding termination used to couple the grounding electrode to a suitable ground location. The ground location may be either on-chip (such as the DC ground of the modulator itself) or off-chip (via an off-chip capacitor, with a wirebond connecting the grounding electrode to the capacitor). The use of a ground shield mitigates the effects that changes in the data rate have on effective length of the modulator as seen by the applied data signal.

20170293182 · 2017-10-12 ·

The present invention provides a display device, which includes a color filter, a quantum dot (QD)-injected photonic crystal film, and a backlight module. The QD-injected photonic crystal film is formed by injecting QDs into a photonic crystal film. Due to the light guiding effect of the photonic crystal, the light emission efficiency of the QDs can be effectively improved. The photonic crystal film includes red, green, and blue light transmission zones. The QDs injected into red, green, and blue light transmission zones of the photonic crystal film are respectively red, green, and blue QDs, so that when white mixed light emitting from the backlight source reaches the QD-injected photonic crystal film, light transmission zones of the photonic crystal film allow only light of corresponding colors to pass such that the QDs contained therein emit light of corresponding colors. Further, these colors of light respectively transmit through the color filters of corresponding colors. Light of other colors is reflected back by the photonic crystal film to be subjected to scattering and re-reflection by the optical film for being subsequently allowed to transmit through the other two light transmission zones of photonic crystal film.
