We propose and demonstrate a simple, potentially low-cost, photonic integrated circuit that can operate as a transceiver in a Ping-Pong optical data-link configuration. The device is designed for uncooled operation, with a gain section, a detector, and. a beam expander inside Fabry-Pérot cavity. The detector has a 1.4-µm quaternary layer with a broad spectral responsivity range extending to 33 nm higher than the lasing wavelength of the device. The transmitter can provide 8 dBm inside a single-mode fiber, and the beam expander relaxes the alignment tolerance to a single-mode fiber.
