  Quantum frequency combs (QFCs) are versatile resources for multi-mode
entanglement, such as cluster states, crucial for quantum communication and
computation. On-chip whispering gallery mode resonators (WGMRs) can generate
these states at ultra-low threshold power. In this paper, we demonstrate the
simultaneous generation of three QFCs using a single on-chip $Si_3N_4$ WGMR
across distinct modal families. We designed a micro-ring resonator with a
radius of 240 $\mu m$, capable of supporting four modal families within the 130
to 260 $THz$ frequency range for consistency regulation. Our results indicate
that, by carefully designing the structure of $Si_3 N_4$ WGMRs, it is possible
to generate quantum entangled frequency combs across distinct modal families
simultaneously using monochromatic pump light. This is achieved by modulating
the pump mode profiles with a spatial light modulator (SLM). Our approach
offers a simple and low-cost method to achieve higher-density entanglement
integration on-chip.
