Optically Integrated InP–Si$_3$ N$_4$ Hybrid Laser
IEEE Photonics Journal, 2016 We describe the first demonstration and characterization of an optically integrated InP–Si $_3$N$_4$ hybrid laser. The laser is formed by integration of an InP-based reflective semiconductor optical amplifier with a Si$_3$N $_4$ based feedback ...

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
