In this Letter, we propose a broadband, nonvolatile on-chip switch design in the telecommunication C-band with record low loss and crosstalk. The unprecedented device performance builds on: 1) new optical phase change material (O-PCM) Ge2Sb2Se4Te1 (GSST), which exhibits significantly reduced attenuation compared to traditional O-PCMs, 2) nonperturbative that enables low-loss operation beyond classical figure-of-merit (FOM) limit.
