Abstract: There is provided a polymer based photonic integrated circuit (PIC) comprising: a first polymeric layer, the first polymeric layer having a refractive index of from 1.3 to 1.8 at a wavelength of 1300 nm; and a second polymeric layer on the first polymeric layer, the second polymeric layer having a refractive index of from 1.4 to 1.9 at a wavelength of 1300 nm and an optical loss of at most 10 dB/cm at a wavelength of 1300 nm. The difference between the refractive index of the first polymeric layer and the refractive index of the second polymeric layer is at least 0.1 at a wavelength of 1300 nm. An interface between the first polymeric layer and the second polymeric layer is patterned with a relief pattern to form a plurality of optical elements. The plurality of optical elements comprises an I/O grating, a 2D waveguide, and a spectral shaping element.
