| Summary: | This paper investigates the LiNbO3 waveguide etalon array which can be used as an optical frequency scale for the frequency standard for stabilization of a laser diode and the filter in the optical frequency domain. In a hybrid configuration made of cascaded fused quartz‐type branch guides, the resonant characteristics are evaluated. an etalon array filter characteristic with good waveguide uniformity is confirmed. Also, the stability of the fluctuation of each resonant peak frequency of the etalon array is evaluated with a frequency standard laser. In addition, a method is proposed for stabilization with a reference laser and an actual operation is confirmed. As a result, the frequency fluctuation of about 20 MHz with only the temperature control of 1/100°C is reduced to ± 2 MHz (corresponding to 1/1000°C) with stabilization by a reference laser. Further, an application example was presented when the present etalon array is used as a frequency substandard. |
