We describe the development of a waveguide platform in the flexible, stretchy polymer polydimethylsiloxane (PDMS). The pliable substrate enables tuning of integrated optical components by mechanical deformation of the host chip, overcoming a key limitation in many bespoke waveguide platforms. We illustrate this capability via the continuous on-chip tuning of a beamsplitter. We also apply these techniques to continuously coupled photonic random walks. Here, appropriate deformation of the chip allows reconstruction the spatial evolution of light in a coupled 1D array by observation of the end face alone. The PDMS platform is compatible with visible wavelengths and is insensitive to polarization, making it a compelling candidate for the integration of quantum optics experiments.
