A New Approach to Measuring Work-Related Well-Being

The main aim of this study was to develop a short questionnaire to assess work-related well-being from the organizational behaviour perspective. The short well-being questionnaire enables measuring longitudinal work-related well-being. Work-related well-being was assessed with a 147-item questionnaire covering both organizational and intrinsic factors of work-related well-being. The questionnaire consisted of 27 categories. The respondents were 114 women (65%) and 62 men (35%), mean age 39.2 years, in various occupations. From the extensive questionnaire a shorter questionnaire with 33 items was developed by principal component analysis. The Kaiser–Meyer–Olkin measure to test the sampling adequacy of 27 factor solutions varied from .62 to .91 and Cronbachʼs α was .74–.94. Most κ values of the shorter questionnaire were .50–.94 (p < .001). The reliability of the short version was comparable to that of the original questionnaire. The short one could also be suitable for Internet and mobile questionnaire applications

4W single transverse-mode VECSEL utilising intra-cavity diamond heat spreader

An optically pumped semiconductor vertical external cavity surface emitting laser, with high output power and excellent beam quality operating at a wavelength near 1.05 mm, is reported. A transparent diamond heat spreader was used for thermal management of the laser.The gain structure grown by molecular beam epitaxy includes 13 compressively strained InGaAs quantum wells. Maximum output power of 4 W with diffraction-limited beam (M21.15) was achieved using a 2% output coupler and incident pump power of 20 W. It is shown that power scalability is feasible with the presented laser geometry

All-Optical Packet Envelope Detection using a Slow Semiconductor Saturable Absorber Gate and a Semiconductor Optical Amplifier

Abstract—We propose a simple and effective scheme for alloptical packet envelope detection (AO-PED), exploiting a slow saturable absorber-based vertical cavity semiconductor gate and a semiconductor optical amplifier. A high extinction ratio of 15 dB was measured for the recovered envelope signal. The scheme is suitable for photonic integration, and is transparent to the packet polarization state and data rate. It also shows relatively low sensitivity to the input packet wavelength compared to previous alloptical schemes. AO-PED is experimentally demonstrated at 12.5 and 40 Gb/s; the recovered envelope was used to drive a 1 × 2 all-optical switch for low-priority packets deflection in case of contention occurring between time-slotted synchronous packets. The deflected packets could be routed to a buffering stage or to a different path, depending on network topology, allowing thus contention resolution without packet loss. Error-free bit-error rate (BER) was achieved for packet payload data at the switch outpu
