We present a low-loss, compact, polarization insensitive 3-dB optical power-splitter for submicron silicon waveguides. The splitter is optimized over broad wavelength span ranging from 1300 to 1700 nm through finite difference time domain simulations. junction footprint only 1.8 × 1.3 ?m, which smaller than previously reported broadband multimode splitters. Furthermore, the demonstrated device ...

Two modes are being considered for a 50 on 50-GeV muon collider: one being a high-luminosity ring with broad momentum acceptance (dp/p of ∼ 0.12%, rms) and the other lower luminosity with narrow momentum acceptance (dp/p of ∼ 0.003%, rms), or Higgs Factory. To reach the design luminosities, the value of beta at collision in the two rings must be 4 cm and 14 cm, respectively. In addition, the bu...
