  • Publication number: 20230299553
    Abstract: A method and a system for generating single-sideband Raman light for cold atom interferometer through phase modulation are provided. The system includes a laser, an electro-optic modulator (EOM), a local microwave oscillator, a narrow-bandwidth optical-fiber filter, an optical-fiber power amplifier and a frequency doubling crystal. The laser has frequency of ? and is input to the EOM. The local microwave oscillator applies a modulation voltage with frequency of ? to the EOM and generate double-sideband frequency-modulated light with frequencies of ?±n?(n=0,1,2, . . . ). This light is filtered by the narrow-bandwidth optical-fiber filter, which outputs the target frequency light and is successively input to the optical-fiber power amplifier and the frequency doubling crystal and yields the single-sideband Raman light for cold atom interferometer.

    Abstract: A single-laser light source system for cold atom interferometers, comprising: a reference light module including a narrow-bandwidth laser and a frequency stabilization module and an optical frequency shift module including a first electro-optic modulator and a first narrow-bandwidth optical-fiber filter. The first electro-optic modulator is connected to the first narrow-bandwidth optical-fiber filter by an optical fiber, and the first electro-optic modulator is connected to the laser by an optical fiber. The first electro-optic modulator receives an initial light from the laser, modulates the initial light by a modulation signal with a preset frequency, and generates sidebands with the preset frequency. The first narrow-bandwidth optical-fiber filter filters the optical signal at the output of the first electro-optic modulator to obtain a frequency-shifted light as the +1-order sideband.

  • Patent number: 11605682
    Abstract: An organic light emitting diode (OLED) display panel and an electronic device are provided. The OLED display includes an under-screen camera display region and a normal display region surrounding the under-screen camera display region. A pixel density of the under-screen camera display region is less than a pixel density of the normal display region. By lowering the pixel density of the under-screen camera display region, and thereby raising a light transmittance of the under-screen camera display region, an under-screen camera and a true full screen display are realized.

  • Patent number: 11374199
    Abstract: A display panel and a display device are provided. Moisture and oxygen can be effectively prevented from passing through an organic light emitting layer in a barrier area and entering the organic light emitting layer in a display area of the display panel by disposing the barrier area having a plurality of trenches between the display area and a through hole and forming a blocking structure through disposing a barrier block between adjacent trenches. In addition, the trenches can be set into a wavy shape, which can increase an area of the trenches and further increase a surface area of a packaging layer in the barrier area, so that intrusion of moisture and oxygen can be effectively blocked, thereby protecting the display area and improving stability of the display device.
