  bibo_abstract:
  - <jats:p>Multimode integrated interferometers have great potential for both spectral
    engineering and metrological applications. However, the material dispersion of
    integrated platforms constitutes an obstacle that limits the performance and precision
    of such interferometers. At the same time, two-colour nonlinear interferometers
    present an important tool for metrological applications, when measurements in
    a certain frequency range are difficult. In this manuscript, we theoretically
    developed and investigated an integrated multimode two-colour SU(1,1) interferometer
    operating in a supersensitive mode. By ensuring the proper design of the integrated
    platform, we suppressed the dispersion, thereby significantly increasing the visibility
    of the interference pattern. The use of a continuous wave pump laser provided
    the symmetry between the spectral shapes of the signal and idler photons concerning
    half the pump frequency, despite different photon colours. We demonstrate that
    such an interferometer overcomes the classical phase sensitivity limit for wide
    parametric gain ranges, when up to 3×104 photons are generated.</jats:p>@eng
