• We demonstrate a monolithic InP-based photonic integrated circuit (PIC) consisting of four tunable V-cavity lasers (VCLs), a cyclic echelle diffraction grating router (EDGR) and four semiconductor optical amplifiers (SOAs). Quantum-well intermixing (QWI) technique is used to produce three different bandgap energies on the chip. Single VCL with 30 nm tuning range at <inline-formula> <tex-math notation="LaTeX">1.3~\mu \text{m} </tex-math></inline-formula> wavelength band and up to 40 dB side-mode-suppression ratio (SMSR) is experimentally demonstrated. The chip has a 4.5 nm channel spacing and 18 nm free-spectral range (FSR). Measured spectrum of all the 16 input-output combinations show cyclic response.
