III-V-on-Silicon Photonic Devices for Optical Communication and Sensing

“…Very good suppression of the side modes is obtained. A similar device was realized integrating the amplifier array with a demultiplexer consisting of four ring resonators with slightly increasing radii coupled to a common bus waveguide [27]. Similar threshold currents, output powers and linewidths were obtained as for the single ring tunable laser described above.…”

“…It is important that they are well designed to have controllable reflection and low transmission loss, especially at the output side of the device. They could e.g., be implemented using a shallow etch step in a locally widened 220 nm high waveguide as described in [27]. Integrating the optical amplifier with a tunable ring resonator allows building a tunable laser as shown in Figure 8.…”

“…The ring resonator based tunable lasers described above typically require a rather complex tuning scheme and are designed to generate only a single wavelength channel at a time. To alleviate this problem, so-called digitally tunable lasers or multi-frequency lasers were demonstrated [27]. They consist of an amplifier array, in this case a hybrid III-V on silicon amplifier array, integrated with a wavelength multiplexing device such as an arrayed waveguide grating (AWG), a series of ring resonators or a planar concave grating (PCG).…”

InP membrane on silicon integration technology

“…IMEC has since replaced the molecular bonding using SiO 2 by adhesive bonding using a BCB polymeric layer which is more tolerant to non-flatness of the bonding surfaces. Using this approach it has recently demonstrated a 4-channel WDM laser that produces more than 4 mW output power in the silicon waveguide [5]. Taper lengths in this approach are comparable to the approach of UCSB, in the order of 150 µm.…”

Unidirectional, widely-tunable and narrow-linewidth heterogeneously integrated III-V-on-silicon laser

“…Heterogeneous integration by means of molecular or adhesive die-to-wafer bonding provides a scalable approach to integrate III-V opto-electronic components on the silicon photonics platform. Several types of laser sources have been realized on this platform, including single wavelength distributed feedback lasers [11][12], multi-wavelength lasers [13] and widely tunable lasers [7,14,15,16]. In this paper we present a novel type of widely tunable laser.…”
